What makes us human? The sequence of the Neanderthal genome has been largely completed -- and we're not all that different from those ancient relatives. Writing this week in the journal Science, researchers compare and contrast the Neanderthal genome with the genomes of present-day humans from different parts of the world. The researchers also found clear evidence of 'gene flow,' evidence of interbreeding between the species. Surprisingly, on a protein level, the researchers found fewer than 100 differences between the human and Neanderthal proteomes. We'll talk about how we're different from -- and similar to -- our Neanderthal relatives.
