Alternatively, Tassie Devils DNA contains unexpressed genes from an earlier time when they bred at a young age. Devils which express these genes nowadays have a better chance of progressing their DNA into the future. This is a simpler concept than epigenetically creating new genes from scratch.
The aim of the research says Gibson, was to examine both populations and determine the effect of "nature, nuture and culture on human physiology".He says the environment includes "the complex mix of what you eat, how stressed you are and where you live"....For the study, blood samples were taken from individuals living in both the city and villages....Overall the study found "gene expression differed between the two locations in up to a third of all transcripts"."The main conclusions showed that, which genes are expressed and how much of each gene is expressed depends primarily on where you live and what lifestyle you live," says Visscher.
Humans have same human genes which by the process of methylation are varied due to our environment starting prior to conception with influences caused by mother nature, father time and choice, which is sometimes seen as randomness.
