Genetic Piano Again

In a prior post Genetic Piano Perhaps someone was listening........ A while ago I posted on the idea that we should look at genes like keys on a piano. The number of tunes that can be cranked out is astounding. Sometimes a single key is played or in combinations. Some are rarely played but still can produce beautiful music. Now someone else has picked up on this idea. More support for IDvolution.

Now from Nature:

Epigenome: The symphony in your cells

A slew of papers reveals the chemical tweaks to DNA in a wealth of different cells — as explained with the help of a small orchestra.

Past 5,000 years prolific for changes to human genome

 

A study published today in Nature³ now helps to clarify when many of those rare variants arose. Researchers used deep sequencing to locate and date more than one million single-nucleotide variants — locations where a single letter of the DNA sequence is different from other individuals — in the genomes of 6,500 African and European Americans. The findings confirm their earlier work suggesting that the majority of variants, including potentially harmful ones, were picked up during the past 5,000–10,000 years. Researchers also saw the genetic stamp of the diverging migratory history of the two groups.
