Human Evolution Theories

animals can choose what to eat and what not lol...if they dont want zebra that day they dont have to eat it

if they dont wont to mate they dont have to
the reason they do is becouse most animales roll in packs..they learn from thier parents on how to live ..so they live just like thier parents


what do think happen........mmmm
lets see what u see..hear....


god was board one day so ...lets make a human....(plop) thier is one (plop) thier is 2 let them mate and creat more....

lol

it started out as orginzems
and evolved to somthing els...and so on...we just go the better half...by saying that i mean we didnt evole into a dog or some thing

u misunderstand evolution so badly that it appears to go against itself to u.

u basically just have alot of questions, but the answers are all explicitly out there.

ur questions such as " why are we the only ones to evolve large brains etc etc" are so juvenile that one who understands how selection works and how biological niches are filled would not even consider asking.

im not trying to be disrespectful, but all of your questions are satisfactorily answered within the theory.

it would be like someone who isnt really understanding of algebra asking questions about it and then prematurely coming to a conclusion that algebra is a discipline that goes against itself.... thats what u are doing.

instead of jumping to a conclusion, u should simply just ask if you are not sure exactly how evolution works, or ask if u arent sure about chaos/random chance/entropy/ laws of thermodynamics and how they are not at odds with biological evolution.

for some reason ppl think that evolution is a "theory in crisis", when this is so far from the truth.. it is in no more crisis than the theory of gravity.

the answer is a loud and firm YES !



its all evolution. see this is what needs to be understood. Evolution is alot more complex tht it is made out to be. There are several different types of evolution and the one main type that is normally argued about is what is known as "macro evolution".

Macro evolution as the name suggests involves a change in the populations gene pool that results in one species over time being modified by cumulative changes resulting in a totally different species (one must have a firm definition of the word "species" in order for this to "gel").

the other type of evolution is what is known as "micro evolution". micro evolution (as the name would suggest) occurs on a smaller scale and manifests itslef as a change in the populations gene pool that results in a change in form, function or ability within the species . An example of this would be birds having different beak sizes depending on the type of seeds they need to eat, but all the while still being finches.. one achetype of finch led to the microevolution of several varieties with different beak sizes based on adapting to the environment... but note.. this change occured because there had to be a change in the genetics ie a genetic mutation! u cant have evolution without having a change in the genetics

thats all evolution is,.. its defined as a change in the genes divided by time (normally plotted on an x and y axis with time on the y)

so if u have one bird born with a mutated beak by chance, this isnt evolution unless this change results in a change in the genetics of a whole population! individuals dont evolve.. only populations.

now more importantly.. its always said how "things change to suit their environment", however the bioogical/ evolutionary defination of the word "environment" could be anything.. thats why evolutionists truly dont use that word like that.. its more accurate to say that creatures evolve based on environmental stressors.. these stressors could be physical or non physical.. not simply implying location.

The experiments done on mutations of DNA make me think that...but hey...don't let science get in the way of what you want to believe.

You didn't answer my questions though- you just played it off like i'm stupid or that I can't comprehend what the theory is about- If my questions are so Juvenile why didn't you just break it down for me?


why is it humans are the only ones capable of rational thought? Why are we the only things not bound to instincts?

lol

you missed my point completeley- animals are born with certain survival instincts that they use

for example- a kangroo's baby instinctivley knows to climb inside it's mother's pouch

and please don't pretend to know what I think about god and the orgins of man-

humans are born with certain instincts too as well

i didnt answer this question because they have been answered so many times in this thread

humans are not the only ones capable of rational thought (rational thought is nothing special.. its only defined as taking in external stimuli, analyzing it with a consistent thought pattern, and then acting on it in a consistent way that ultimately will lead to more benefit than detriment).. we are not the only ones to do this by a long shot... any creature with as suitable central nervous system with a complex nueral network can do this...

we also are not creatures that are NOT bound by instincts. we follow natural instinctual behavior and thought patterns on the regular.

there is truly no way to tell

evolution doesnt have to imply a step "up" in complexity. it simply is a change in the genes..

but from current trends in mating patterns and cultural blending and societal pressures, it is seen already that human height has increased on average of about a quarter of an inch each 60 years or so.. (this may not seem like a big deal but this is amazing!)

In additon, over the last 70 years or so the human thumb is getting closer to the index finger (the reason for this is not known, however it is theorized that over the past 70 years, women are becoming more attracted to men who more than likely have job functions that utilize less thumb strength!) thus in the process the resultant offspring carry the inherited trait of decreased thumb strength and ultimately this manifests itself as the thumb migrating closer to the ijdex finger by way of loss of musculature!

who knows, if this trend continues for another 50,000 years we may not have thumbs at all.. it could possibly fuse with the index finger.. especially since most ppl dont need thumbs for typing and as technology increases the need for physical strength will be a thing of the past!

and then guess what will happen 50,000 years from now... some human will be born with a fully formed developed thumb appendage (by way of genetic birth defect) and then people will debate over the thumb being a vestige of prior evolution!

ultimately, humanity will nevert evolve into a totally different species until there is some sort of biological or geographic isolation between different human populations fo rlong periods of time.. but being that we are a global community this is unlikely to happen until we colonize space!

the evolution of humans brought about by the colonization of space, and the enviromental stresses of living on other planets. id like to see that.

and il be damned if i have kids without a thumb. we need our thumbs thumbs are



the type of evolution brought on by spce colonization would be a mixture of adapting to a new physical environment in addition to a genetic mutation that would change the sexual properties of our gametes (sperm and egg).. so if w sent up a colony in space say to Jupiter and they stay isolated from earth for about 20,000 years and have a genetic code that now incorporates this slight change in our sperm and egg, when they finally do meet up with an earth born human they will not be able to mate because the space sperm will not be congruent with the earth egg. This is how most likely it could occur.. thus the jupiter human's would be a new species of human unable to mate with earth humans due to biological and geographical isolation.

dont worry, none of our kids will be born without thumbs. im talking about kids 50 to 100,000 years from now... in addition, thumbs are only important to us now in the environment we live in.. in fact the whole concept of a physical body with a skeletal system is only important because we live on earth.. everything is relative.. if we were on a diff planet with different gravitational forces , a physical body with an internal skeleton would be detrimental in many cases!

rational thought isn't special? are you serious? Why do humans have a wide arrange of emotions? why do we question our existence? Why do we question our orgins?

I agree with that we follow natural instincts- that's why we mate, we have a survival intinct from birth to nurse from our mothers

but aside from that we can make choice that would go against instict- we're not programmed to just eat meat, we can abstain from sexual intercourse, we can make choices at the drop of hat to end our own very existance

It is our ability think freely that sets us apart from almost all animals, it's our free will that breaks our bonds from nature.

have you've been studying evoulution so long that your convinced it's absolutley the truth? Your a scientist so you do know that evolution is still therory- meaning there isn't enough evidence to confirm that it is the absolute truth. Have you ever stepped outside the box to look for evidence that could disprove the theory? Sureley with your knoweledge of the subject you would be the best canidate to do so.

^^how do these "hobbit" creatures fit into the evoulution of man?

^^how do these "hobbit" creatures fit into the evoulution of man?


lol the same way midgets fit in are time ......thier are still alot to be found in evolution..as thier are lots of years inbetween then and now.......its like now......in diffent regions of the world will have diff types of birds same with humens..we have diff types of skin
evoulution is more then a theory since thier are artifacts of it

the same with the dinosos....so it more then theory its life ...its real
but u cant seem the except ur ansesters were monkeys lol

just like the reptiles of 2day.. dinos were thier ansesters
known fact

take that home and chew it up.....its delishes

its plausible but unlikely due to our evolutionary past from small mammal to walking primate

i agree that our mode of thought is different from other animals.. but this is only beause of the way our central nervous system works in conjunction with our nueral network.. its nothing special about it..

so is ur argument that " because we can think and make certain decisions.. we are thus special and not the product of evolution"... thats silly

i step outside the box every day.. honestly in a scientific discipline that relies on new and incoming data there is no box ! one must always have an open mind and be willing to evaluate whatever is "new".. however, to thhis date there has been nothing that violates human evolution in anyway shape or form.

if new primate remains are found.. they fit nicely into the human evolution story!

the question truly is... do u ever step outside ur box?

For the masses who use god as an explanation for their existence; try taking it to the second step...OK, here's the question...Where does god come from? Oops, right back to square one eh? In simplifying your existence to explain why you're here, you've actually complicated the matter, but you chose to stop there because God is all you need to know...no need to think further.

At the beginning of your sentient god's existence, how did he answer the following question to himself, "hmm, why am I here, where did I come from?". Perhaps he explained it in the same manner you have...ahh, a never ending loop with no beginning...I see, it's all clear to me now...god is hogwash. Life isn't a dress rehearsal, this is it...heaven, hell and purgatory are all to be experienced in your lifetime...live life to it's fullest now, for when you die you won't have the ability to ponder why you were wrong...there is no afterlife, there is no god. The god we know is the god we made.

---

that my friend is totally plausible.. as long as if these early mammals were influenced in some sort of way that their genetics reflected this change.

for ex.. if early mammals had the privledge of meeting up with human aliens that are already bipedal and then they thus imitate the bipedal walking because they see it as beneficial to life on earth.. and this leads to bipedal walking mammals on earth.. its possible.. but there is no proof for this.. but anything is possible

this is what is known as the "First Cause" postulate.. i have never heard a creationist answer to it to this day :)

The question doesn't need to be answered if you don't believe in a god

as of today.. the data that suggests why tetrapods became bipedal is due to the evolution of color vision.. coupled with a change in diet, coupled with a change in geopgraphy..

if a creature can stand up for short stints and reach apples in the trees and possibly walk while holding them, these gives a tremendous survival advantage compared to other creatures that cant do this.

it happens over a long period of time.. bipedalism is both a learned behavior and biological behavior.

i agree, but it would seem to me that those that do would be curious enuff to ponder this question... but most just simply blow it off by saying.. "oh, god is god.. there was no beginning to go"

but we know thats just foolishness in thought

how would color vision aid to upright walking mammal?
the rest of it i understand, kind like when people do trick with there dogs to make them stand on hine legs to grab something. eventually a dog can learn to balance and walk further distance like that or use it to aid in a situation to get something they can tell is out of reach.

That would be total ignorance. Some of my friends are religeous and it makes talking about serious matters not fun. The answers to my questions are always "God wants it that way, God works in mysterious ways"

Brainwashed.

color vision is important to a creature that is mainly an herbivore.. being able to see colors (ie wghich fruits are riper than others) is a great benefit...now reaching for them was the next step

pretty much :)

Yes !

if the selection pressures (environmental stressors)
are strong and consistent enuff (ie we do it all the time with our seletive breeding and bacterial vaccines)

i guess.. i never watched star trek but what u describe is an example of "artificial selection" and thats what im talking about.. but keep n mind.. the star trek blob was a single creature.. "artificial selection" only works on a population of creatures that keep reproducing

because remember. the key to it working is genetic variation/diversity

Yes !

what u need to understand is that thre basically are no limits to what can happen as long as a creature reproduces by sexual means (sperm meets egg and in the process an exchange of genetic material and information between 2 parties) thus creating genetic diversity.

hypothetically, i cat (which is a tetrapod mammal) could be selectively bred in such a way that u decrease its body weight.. the next step would to be to apply environmental stressors to increase forearm strength... the next step would be to decrease hind leg muscle mass...... the next step would be to modify the forearms so that they somewhat develop an enlarged skin appendage between the abdomen and elbow

if this could be successfully carried out u could have a flying animal whose ancestor was a pet cat.

its not that hard to imagine.. i mean after all.. modern bats are nothing but modified tetrapods that were once regular walking mammals.. its all the same thing!

wiat a sec.. dont over simplify it!

dont make that mistake in your thinking!

it wont be a creature sprouting wings! it will only be a creature with modified arms that are able to serve the function as wings.

remember.. bird wings are nothing but modified dinosaur arms

like say you have a food source over wide gap the only way to reach it would be to fly.
the situation would breed the need to have wings to get to the food source.
but wat could actually start the process of the animal changing?

---

nahh thats not how it would work exactly

lets say there is a wide gap or cliff like u say that has precious food.. and u are a 4 legged animal.. u try to jump and u fall to ur death..its just simply too far..

but then the rest of ur population keeps reproducing and lets say that the males who get all the females just so happen to have the strongest arms...thus all of the offspring have this gene for strong arms..

1000 more years pass and by chance there is a genetic mutation that adds an extra strip of muscle and flesh between the arm and body.. this creature finds that this xtra flesh allows it to jump higher and further..

the females of the colony notice this and all flock to mate with this creature. luckily this mutation is inherited in all the babies... leading to a population of creatures who can now jump real high and far (becaus ethe extra skin coupled with
the increased arm strength acts sort of like a parachute and makes them "glide" in the air a bit.

1000 more years pass and eventually thru natural selection, the creatures that have the fleshier arms and strongest arms live longer and have more babies than those who have weak arms........

now the stage is set for an evolutionary event to occur!...more time passes and eventually the creatures discover that if they move their arms back and forth a bit while jumping that they can somewhat glide alot longer and farther!

they keep doing this and it is a learned behavior passed down (in adition, the males that can do this the best get all the ladies and thus pass their genes on)

the end result years later are a population of flying mammals that are now able to reach the other side of the cliff.

exactly !!!!!!!!!!!!!!!!!

now ur gettin it

and this is where people start to get upset.. because they dont want to think about complex things arising from random luck!

they want life to be more "special" than that.. when in actuality there is nothing really special about life (speaking objectively)

..now in that example we just went thru.. u must realize that it took so long and was left to luck because it was natural! (not controlled by anything other than mother nature and random forces)

however, if lets say, humans were there to help guide this evolution .. it could occur much faster (because we would set out with the specific intent to increase their arm strength.. etc)

legato.. we do it everyday

do u think a pit bull terrier or pink pig is "natural"?

also, thru our continued use of pesticides we have created a whole horde of super insects that are evolutionarily immune to RAID and COMBAT

also.. why do u think we have to keep taking flu shots year after year?..

this is true......ur pretty smart timbs

evolution is a every day thing ...we see it as u just told it ...as in the super insects...that are immune to posions ........and with the flew.......bird flew growing o so strongly...it hasnt evolved to the passing from human to human through air but it will soon...like the

black plage ..................what will the non belivers belive about this...the evolution of commen colds and sickness that we creat and are creating super colds..and so on from daily meds....
what do they call that

gods way of saying were in for it

lol @ "gods way for saying we are in for it".. thats funny.. but not too far from the way many think.

but seriously, i guess the problem is that people desperately want to see a verifiable form of a creature turning into another one right b4 their eyes.. but that will never happen in that way in our life span.

no problem :)

u are correct.. evolution isnt all about monkeys into man..

evolution explains everything about the world we live in.. all of nature and all of life is controlled by evolution.

u cant study life and biology without understanding evoluton

I don't need to see an animal transform before my eyes. But I hoesntly don't see any of the evidence that I should be seeing if it did happen?

another good evolution state of fourm would be a fish......a fish that can breath air and can live on land.....its around ...its the snake head fish....thats evo...fo sho
they are spreading alot around hear on the east coast
mostly in md...its from china or some shit....

thier is evidence

look that fish up .....snakehead fish....i think thats the name

this fish dosnt need water it can live on land for 2 to 3 good days and it prays on small animls like cats and shit

no lie ...this shit is in the news alot around here

So what ^

I owned axolotls. They have one lung and gills. Doesn't mean they evolved out of a fish.

the evidence for evolution is everywhere on this planet.. everytime we look at any organism we are studying and admiring evolution.. to blindly deny evolution on a basis of " i dont see any evidence" is just plain unexcusable at this point in human history.
