Study offers first global picture of the evolutionary origins of proteins

Each cell contains thousands of proteins, each one of which bears a unique signature. All proteins, distinct in shape and function, are built from the same amino acid strings. Many proteins are vital, as evidenced by the plethora of diseases linked to their absence or malfunction. But how exactly did proteins first come to be? Do they all share a single common ancestor? Or did proteins evolve from many different origins?

"A substantial fraction of the Neanderthal genome persists in modern human populations."

I just KNEW there had to be an explanation for my son-in-law!

You're up late or early. =)

Another interesting tidbit, we may get lighter color skin from Neanderthals

Neanderthal lineages excavated from modern human genomes

Summary:

A substantial fraction of the Neanderthal genome persists in modern human populations. A new approach for analyzing whole-genome sequencing data from 665 people from Europe and East Asia shows that more than 20 percent of the Neanderthal genome survives in the DNA of this contemporary group. Significant amounts of population-level DNA sequences might be obtained from extinct groups even in the absence of fossilized remains, because these archaic sequences might have been inherited by other individuals from whom scientists can gather genomic data.

Summary:

Our most recent common male ancestor emerged some 209,000 years ago -- earlier than many scientists previously thought, according to new research.

Lilith rocks. =)

LILITH   f   Near Eastern Mythology, Judeo-Christian Legend
Derived from Akkadian lilitu meaning "of the night". This was the name of a demon in ancient Assyrian myths. In Jewish tradition she was Adam's first wife, sent out of Eden and replaced by Eve because she would not submit to him. The offspring of Adam and Lilith were the evil spirits of the world.

I always thought it was Lilith!
