Our Social Lives and Our Genes

Monday, August 26, 2013

David Dobbs explains how epigenetics works and looks at how our social lives affect our genes. Studies have shown that our genes are socially fluid and social isolation can be deadly. His article “The Social Life of Genes” is in the September/October 2013 issue of Pacific Standard.

Tom Li,

By junk dna I suspect you are confusing intron protions of DNA with non dna molecules.

Wikipedia: epigenetics is the study of changes in gene expression or cellular phenotype, caused by mechanisms OTHER THAN changes in the underlying DNA sequence—hence the name epi.

Eugene, Yes its part of the DNA, its basically some of the "other stuff" on the DNA helix that was considered to be "junk" when first noticed...but like everything else in the Natural World there is no such thing as actual/true junk. Turns out a lot of the things we think are our free-choices, like tastes preferences, smell aversions, colors we favor or disfavor - are biologic in nature. These have been found thru epi-G research to answer the "what is that stuff?"

How did the epigenetics process evolve and to what purpose?
Does it appear in all living things?

it could laos be testosterone that gets boosted.. fish are also known to change gender in the absence of males a female will masculinize....

I believe this is also the case in humans with regards to things such as racial gene expression.. not so much socially as your race is what genes you express rather than the pool you are
