Question about the evolution process..how exactly would a man evolve from a primate..what is the process?

The Plesiadapiformes lived about 55 million years ago. These were rat-sized creatures that had crude grasping digits and side facing eyes. The first phase is an increase in mass accompanied by increased visual capabilities. The eyes became forward facing for binocular vision and two-spectrum color vision arose by the time Old World and New World primates split. Three-spectrum color vision developed before most the Old World primate lines split from the main group. The monkeys and apes divided with apes developing a looser shoulder girdle. Further mass increases in both monkey and ape lines favored progressively shorter tails as prehensile tails could no longer be weight bearing. The apes continued to differentiate. The orangutans/gorilla line could be characterized from the human/chimp line by a variety of mutations including the CYP21A locus involved in steroid hormone production. The pre-human line moved from forests to plains. Several favorable feedback loops shaped the current human form. Walking erect enabled more control of height for scouting/hiding while freeing the upper limb for delicate tasks such as throwing and tool making. The hand flattened, become more versatile but less effective for tree climbing. Tool making enabled hunting, which created a higher protein diet, which enabled more brain development, which made for better tool making. Skinning enabled survival without hair and a mutation in the KRTAP23-1 hair collagen gene appears not to be deleterious. This is a simplification, but summing up 55 million years and millions of generations should not be easy.

Evolution is just change over time. It has been demonstrated that organisms change over time so it is not really an issue that is in doubt. By far the most reasonable and logical explanation for why animals change is described by the phrase "survival of the fittest". There are several ways to define that but in its simplest form it just means that the most fit animals will be the ones that will survive to have offspring and their traits will be expressed in later generations in higher numbers because more of the fitter organisms will survive. When something like a tail is no longer needed it will tend to disappear. The animal that doesn't grow it will be at an advantage because it takes less energy to grow up. He didn't waste it on a tail. A reason he might no longer need a tail could be that he started swing from his arms because he became too large to swing from his tail. That is probably basically how the first apes began, as a large monkey that didn't use their tails anymore. Why we lost our hair is a very controversial subject and there have been many theories. Most used to think we lost hair to cool off but that is not the reason I think we lost hair. I think it was more sexual selection and wearing animal skins that contributed more to it. When you loose your hair, you will not have as many lice and that is also a great benefit. You loose physical protection from sunlight and branches so I am of the opinion that it is a more recent adaptation of the last couple of million years. The brain getting larger was thought to have occurred because we started scrounging for bones and got a large supply of lipids needed for a large brain. If that were totally true than vegetarians would have smaller brains. We probably started growing larger brains about 3 million years ago and it was because of social pressures and hunting that drove the selection of smarter hominids. Evolution is driven by selection. There needs to be an advantage and that advantage is not always bigger or more complex. It is just something that helps a particular organism survive.

To give you an idea of how a single change can have a huge effect, you can look at the ASPM gene. There is a similar gene in humans and other primates with part of the gene called the IQ domain which repeats multiple times. In humans, there are more repeats of the IQ domain than in other primates and the result is that the number of neurons increases more rapidly in develpment and the brain grows 3 fold in size. Some people have a mutation in this gene and they are born with a condition called microcephaly, or a small brain, and severely deminished mental capacity. So, it looks like a small mutation in a single gene could have been responsible for a large increase in brain size and function between chimpanzees and humans. This mutation did not require the miraculous creation of some totally new information - just a copying of information which was already present. That is just one small but important step in the evolution between apes and man.

I heard one compelling theory that evolving to walk upright preceded the expansion of brain-size. To all you creationists: More and more humanoid-like species seem to be discovered every year. Well I guess God must of ****ed up when he "created" all those obsolete humanoid creatures that didn't fit into his grand plan. (Oh yeah! I get it! They were all wiped out in the big flood!).

Through a long series of mutations. Since there are about 15 million mutations that now separate mankind and chimpanzees, and mutations occur at a fairly constant rate, about 7.5 million mutations have taken place since our common primate ancestor. Many of these have been documented in the technical literature [examples, refs. 1 - 3]. An overview of the process is available in Dawkins [ref. 4].

Evolution is a bunch of BS... Your question explains it all. How the heck would we evolve from tiny tiny little specs of organisms to every single little animal on this earth!? I mean, it's not just religion here, it's common sense

the only time it will happen is when they adapt on their climate and place. But the thing is..man is so versatile that they don't have any evidence that man evolved. thus Evolution is just more likely a fiction now... and that's the reason why it contradicts the Genesis. Because man cannot accept supernatural and out-of-the-void explanation.

It was simply through adaptation. what i mean is that say if a group of primates migrated to an area with warmer temperatures primates with less fur would better survuive. so if someone was slightly mutated and they survuived better they could go on to reproduce making more offspring like them and the process keeps repeating. i hope thats a good enough answer i know a lot more but to lazy to type.

It was too long ago to know the exact details, but if that TV show Cavemen comes out this fall, maybe we can ask them.
