Do you believe in monogenism or polygenism?

[Anarchist420]

Poll time!

Monogenism=we come from one

Polygenism=there is no original common ancestor of all.

 

[ElFenix]

most recent common ancestor lived probably in eurasia 15,000 to 5000 years ago.

So my understanding of evolution is basically the dominance of either a mutation or previously recessive trait over another competitor in its population. This means that natural selection doesn't occur until after the organism is born (because the trait wasn't expressed in the parents), so local stimulus doesn't really account for it (meaning the organism survives/prospers because of the stimulus, instead of being born because of the stimulus). This would lead me to believe in monogenism, unless by some random chance the exact same mutation/recessive trait was expressed during the same generation in separate populations. What I'm basically saying is that evolution (at least the mutation/recessive trait part) is random, so it would make sense that just 1 person originated the homo sapien species.

Monogenism is usually referring to languages.

This would bring up topics in the bible also like the Tower of Babel and all life starting with ADAM and EVE. Then it would also go to the possibility of a world-wide flooding event.

Also one might ask where all the natives in South America came from and how they got there. I just find this very interesting. For instance where were the oldest civilizations in South America. Also where did the native inhabitants of Australia come from.

 

[Matthiasa]

Kind of, considering we were nearly wiped out in the past as it is. But really we are all probably related to the first animal that showed traits that with time became advantageous enough for us to have become our own species.

 

[shira]

At the very least, we had to have come from two. Unless you believe that early humans were exclusively parthenogenetic.

 

[piasabird]

I have often wondered why I dont speak Swahili or some other African Language?

Then there are the other races like Chinese?

Parthenogenic Is that like an A sexual Race? We all originated from a race of Amazons?

I am looking up these terms. Me Can Read-um.

I was reading a book a while back and I came accross some Indian Legends from Native American Tribes on the East Coast of the USA. They fed the pilgrims and later it is believed traditionally that the pilgrims started the Holiday of Thanksgiving. However, according to the old legend the natives in America up and down the east coast had arrived on the American Continent from some sort of Island Nation after a great flood and wherever they established on the east coast they gave thanks to their God and even built temples. I could not find any dates on this subject.

This is from the book called "He walked the Americas".

Might have roots in some of Bankcroft's Books.

Here is reference to the book:

[Throckmorton]

WTF are you people talking about? We all are descended from a small population of humans in Africa.

If we evolved from different subspecies of humanoids, then we wouldn't all be the same subspecies now. Then again some of the people on this board make me wonder...

 

[piasabird]

Instead of using Genetics some people have studied this by examining languages and tried to point back to a common or root language. This came up when I was studying in a class called "Western Civilization I"

I find it hard to believe that the Chinese evolved from some African Race.

When you ask some kind of Vague Question expect Vague Answers.

You sure are ignorant for an atheist!! This has nothing at all to do with religion or atheism...sad...and here i thought all atheist were smarter than us run of the mill people who believe in a God...

No amount of "belief" makes any difference here. There is either evidence to support it, or there isn't.

 

[piasabird]

This is like someone anouncing that they found cro-magnum DNA in some rock star's DNA screening. It is a kind of a stretch to prove. Even if it is a joke. So you find some skull that you assume can be dated back to say 5 million years ago. How do you really know it was even human? At best you are guessing. The real truth is that there is no way to even date something that old.

omg fail

 

[Anarchist420]

Well, I think that some of us come from neanderthals. But then, I did some more reading on the subject and neanderthals have a common ancestor with modern-day people (cro-magnons). The cro-magnons were african and the neanderthals were european and asian.

I kind of believe that the animal kingdom is made up of the other kingdoms.

There is evidence to support what's called a "Mitochondrial Eve" - meaning a single female antecedent for everyone alive today. This doesn't mean this individual was the only female. But rather that she is the only female whos offspring are still alive today.

There's also some evidence for a 'Y chromosome Adam' - though in genetic terms, this particular Adam and Eve conbomation lived a long time apart from each other.

 

[Monster_Munch]

I think if you go back 3.5 billion years or so there was some self replicating molecule that is the single ancestor of all life.
