"The genetic evolution of humans in the very recent past might in some ways be linked to the cultural evolution," he said.Other scientists urge great caution in interpreting the research.If those genes don't work, babies are born with severely small brains, called microcephaly.Using DNA samples from ethnically diverse populations, they identified a collection of variations in each gene that occurred with unusually high frequency.
Lahn's own calculations acknowledge that the microcephalin variant could have arisen anywhere from 14,000 to 60,000 years ago, and that the uncertainty about the ASPM variant ranged from 500 to 14,000 years ago.She is not only a naturally sexy ebony, but also mixed with Brazilian—feisty and sexy! Munachi Gail Teresa Abii Nwankwo Also known as Muna, this famous model has now moved on up to rapping and the entertainment world. Megalyn Echikunwoke Megalyn is a very beautiful, petite, and talented American actress, coming from mixed ethnicity parents—half American half Nigerian.Although she grew up in Washington State, she definitely shows her unique roots in her stunning appearance and leaves much for the imagination. So suggests new research that tracked changes in two genes thought to help regulate brain growth, changes that appeared well after the rise of modern humans 200,000 years ago.That the defining feature of humans — our large brains — continued to evolve as recently as 5,800 years ago, and may be doing so today, promises to surprise the average person, if not biologists.
