Nina Jablonski breaks the illusion of skin color

http://www.ted.com Nina Jablonski says that differing skin colors are simply our bodies' adaptation to varied climates and levels of UV exposure. Charles Darwin disagreed with this theory, but she explains, that's because he did not have access to NASA.

Michael Bolton broke the illusion of skin colour for me. Cracker sounds black on the radio.

Many of our foods (especially milk and orange juice) have been Vitamin D fortified.

"Cracker"? Sounds like a racist comment to me......

No. We should mix so we have the best of both worlds. Vladimir

It seems the conclusion is people should seperate themselves based on skin color.

I don't think many would find it bad.

[SIMKINETICS]

Ethnic physical differences were likely a product of adaptation to environmental differences in localities of relatively immobile populations over tens of thousands of years. Now, that immobility is rapidly declining, leading to mixing that might reduce genetic diversity in some important ways. It seems that geneticists should study what this recent trend means for the probability of our survival as a species, especially considering rapid climate change.

whats up with the voices at the end, i feel like im living in Donnie Darko

HAAAAAAAAAAAAAA

lol its way more complicated than that but today we can use embyros to make human clones potentially with simply using a median - oil, water - the stem cell from something as simple as skin - electromagnetism and BOOM there you have a clone, now of course its not as simple as it sounds but when you briefly describe something then of course it sounds simple when you leave out the details - not defending the clay theory i just believe its servery misinterpreted as today humans are making life

A theory is falsifiable, meaning if it is debunked it is no longer a theory. Your claims of it being debunked are erroneous. You are asking questions regarding several different major things, which are very easy to study, you just don't want to. You can find academic textbooks explaining evolution, the big bang, and possibly abiogenesis which is not at this point a scientific theory. Your questions are not good questions, we don't know what caused the big bang, but that doesn't mean god did it.
