I'd like to hear peoples ''serious'' thoughts about just how did we evolve from the genus class of ape known as Australopithecus to become the different class of humans that have existed on this planet? Sorry i don't buy into either the ancient alien theory nor the bible creation myth as both of them are false by just the mtDNA Haplogroup science alone which shows that all humans (Sapiens) came from ''Mitochondria Eve'' some 180,000 BCE and not the ridiculous 6,000 to 8,000 years ago time frame that either those other two groups would want us to believe.

That being said i admit that i'm perplexed as to why any other intelligent mammal (other primates, elephants, dolphins, canines, felines etc.) didn't evolve into a ''human'' during the Pleistocene Epoch (2,588,000 BCE - 11,700 BCE) or at least into the intelligence that we humans have displayed over the thousands of years going back to when we were Australopithecus hominids?

My own thought is that evolution was driven by opportunity and necessity. Our ancestors were in the right place concerning climate, ecology, etc. and there was something that forced evolution on them for survival.

A quick example would be color vision. If competition for ripe fruits was heavy, and most of the population was either monochromatic (totally color blind) or dichromatic (only able to see blues and greens), the rare individual who was trichromatic (could see red, blues, and greens) would have a huge advantage over the competition for gathering ripe fruits faster. This would lead to that individual being healthier and stronger than the competition, thus much more likely to mate and to pass on the trichromatic gene to their offspring.

Thanks for posting JimRom ... and yeap i was pondering about if a diet change might had ''sparked'' the molecular dynamics that kicked evolution of humans into motion. One thought was that maybe evolution was slowly shedding the fur coating of these certain hominids to which over time allowed UVB radiation to penetrate the now bare skin and turn 7- Dehydrocholesterol into vitamin D and from research into vitamin D is that it seems to really be connected with a whole host of genetic and epigenetic changes in the human body.

I think that sapience is very uncommon and requires the right neural architecture to happen.

We don't have a clear idea how intelligent cetaceans are. Specialists say they're highly intelligent and empathic. Empathy is a "human" trait.

Yeap i'm thinking that i've read somewhere before about how dolphins can count (?) and i wondering if we've aquired empathy even back to when we were hominids (animals) as it seems to be a mammalian trait as for example ''mothers'' caring for their young.

Empathy is a great species survival tool. It allows for mothers to care for their young and a tribe to assist each other
what is fascinating is H Neanderthal evolution...from the time they appeared on the planet, they never evolved beyond the technology of simple tool use. H sapiens went from a stone age to exploring Space so far, because of neurons and a highly developed brain. We do not have a well preserved Neanderthal brain to study (although I have met some people who appear to be quite close)
I would suggest that over a period of time, having a few more neurons in the brain of one Australiopithicans to another became a desirable trait, not on a conscious level as we think of it but do to an ability to react faster and thus breed more effectively, therefore increasing the "IQ" for lack of a better term within the species.

So it was about more neurons, rather than brain size? Because the Cro-magnons had larger brains that we do.

I do know that chimps have excellent memories according to tests done.

I seem to remember a recent article where Neanderthals had a "factory" going, making sharp tools.
