Working Title

http://www.lrb.co.uk/v38/n17/steven-rose/how-to-get-another-thorax
This is an article from The London Review by Steven Rose on Epigenetics, which has to do with influences beside the genotype on phenotype, such as environmental influences. This topic is quite controversial as there are strict "fundamentalists" who believe in the overriding nature of the gene. Epigenetics might explain differences between genetically identical twins. Epigenetics is also providing a way for Developmental Biologists and strict Geneticists to have a conversation. Siddhartha Mukherjee wrote a piece in the NYer on Epigenetics that is inciting many corrections and responses. In any case, the issue is by no means settled.

This is an article from the NYT about an article published in Nature recounting the discovery of a single mutation in the DNA indicating that all non-Africans trace their lineage to a single population emerging from Africa from 50,000 to 80,000 years ago. This would have been one dispersal, although there were more, but these are our ancestors. Three research teams sequenced the genomes of 787 people, including Basques, African pygmies, Bedouins and others.

What this means actually is that the genetic material of a donor is in the genetic make-up of the offspring in addition to the genetic material of the two conceiving parents.  The mother had mutated mitochondria so the nuclear DNA of the mother was moved to the egg of a healthy donor after removing the donor's nuclear DNA.  This method was tried in China 30 years ago.

http://www.nytimes.com/2016/09/13/science/south-african-mine-life-on-mars.html?_r=0 This article from the Science Times is about microbes in a South African mine. A Princeton-led team is examining a methane-fed community of microbes which could be similar to the community on Mars. There is a theory that life originated on Mars then traveled to earth by way of meteorites. This is called the earth's deep biosphere.
