does anyone here have good knowledge of science so as to know if humans really have the same ancestor with apes?
I mean,really once upon a time it was the same being?

if so,why it happened only that creature to evolve and develop such intellect and speech?why are there no such supperior mammals like humen,coming from the ancestors of sharks,lions e.t.c?

To answer the question we need to understand how the human mind works and brings about consciousness. Sadly no one on earth does except Jesus and He's not talking...

Go read a fucking textbook. There is a massive amount of fossil and genetic evidence and this is a settled fact.

Why would you expect it to happen? Evolution is dependent on mutations which occur randomly. Complex behaviors and organs don't just happen because they are beneficial.

I studied evolutionary biology
>I mean,really once upon a time it was the same being?
Not exactly. Chimpanzees and bonobos are believed to be our closest relation in the ape family. Long ago, the ancestors of chimpanzees and the ancestors of humans were the same species, which was not a human or a chimpanzee. This species grew and spread until the two populations diverged and continued to evolve on their own in different ways until they became two distinct species. So yes, they did originate from the same original breeding population, but that population was neither human nor chimpanzee.

>if so,why it happened only that creature to evolve and develop such intellect and speech?
Lots of creatures possess intellect, and/or speech. We are just one that happened to develop both. Those features, along with our life cycle and use of thumbs has allowed us to create complex technology and eventually civilization.
>why are there no such supperior mammals like humen,coming from the ancestors of sharks,lions e.t.c?
You need to rethink your definition of "superior". How do you define that word? Most likely you're using an anthrocentric definition, but what we value may not be the same as what's valued by other species. From an objective viewpoint, other species may be called superior.

>>7745926
Evolution is only capable of tweaking what's already there bit by bit over time, there is no inherent plan or direction to the process. Eventually you get these huge changes but every generation was just what survived well.

Perspective is another thing. There even being a sapient species emerging in any particular tree of life could be extremely unlikely, like a trillion trillion trillion to one and yet we would still be here because that past is necessary for us to have a perspective at all.

No, OP, it's a Jewish lie. Everyone knows the earth is only 6000 years old, it's right in Genesis! Consult your Christian brothers on >>>/pol/ for more information.

It's almost decent for Homo Sapiens, but it ignores the many extinct species of humans and dead ends along the way to the present day. It gives the impression of a March of Progress, when it's really poking around in the dark.

Who cares? If someone asks you for your family history do you tell them about all your dead great aunts, uncles, and cousins? Or do you tell them about your parents, your grandparents, etc?

Asking someone about their family history and asking about the history of mankind are two very different things. It's even worse when you consider something like OP's question. Humans, alone, gaining intelligence in a world of dumb animals is strange and doesn't seem to have an obvious answer. When you consider the branching, meandering path evolution took with the great apes as a whole, it's more obvious. Some branches get more social and brainier, some seem to regress and grow less so. It just happens that having a small amount of intellect, learning, and building a collective knowledge is so overpowered in the game of life, that we're all there is to see anymore.

If you asked an Irishman in the states about his family history, wouldn't you expect to hear about the potato blight?

Didn't say it was inaccurate. It's unhelpful. If pressed, could you pick out which were the outcompeted aunts and uncles of modern humans, and which modern humans are directly related to?

There is a good fossil record, pic related

And it's likely that features such as opposable thumbs, becoming bipedal and being omnivorous likely facilitated the ability to develop intellect and speech.

This guy >>7746106 has it about right. Evolution isn't a straight line, it's more like a fractal pattern, constantly branching with different lineages and dead ends. In theory you can trace all life on earth back to a Last Universal Common Ancestor, a rudimentary single-celled organism somewhere in the Paleoarchean era. For humans and apes? There's several points/species that could be considered a last common ancestor: the earliest would be the point where the Hominidae branched off from the rest of the primates, then there's the Homininae divergence (the split between the pongids and the Homininae, or in simpler terms between orangutans and human/chimp/gorilla ancestors), the point where the Homo genus branched off from the Hominini (home of Homo, the chimpanzees and the australopithecines)...

>> No.7746600

The picture is not explaining the entirety of mankind, it is simply a picture displaying the lineage from common ape-like species to man. To say that it's inaccurate or ignorant is simply wrong.
