How old are homo sapiens?

According to Berkley anthropology there is a human skull that was discovered to date back 160,000 years.

5+ million years according to berkley as well... depends on what you call "human" - hominids date back to before 5 million years ago.
ByGod :)

The lineages of humans and chimpanzees, our closest relatives, diverged from one another about 4.1 million years ago, according to a new estimate that is said to be far more precise than previous ranges for this critical evolutionary moment.
