New research has found that changes to bodily RNA can be transferred to spermatazoa and hence to offspring. This “[collapses] the timescale necessary for the transfer of genetic information through the germline of a species (e.g. sperm) from hundreds of thousands of years to what amounts to ‘real time’ changes in biological systems.”
For me it would explain, for example, how human beings have managed to evolve such varied racial features in different parts of the planet, although under classical models of evolution there has not been enough time for this to happen since homo sapiens left Africa only about 200 thousand years ago and spread across Asia only 75 thousand years ago.
The findings also reinforce the view simply that we are all part of one large interconnected organism. This organism has become increasingly differentiated over the past 3.5bn years (when the first differences appeared in the Last Universal Common Ancestor or LUCA that once covered the planet), but it still co-evolves as a single interlinked organism, via an interconnected Escher Cycle of different mechanisms, of which these new findings are merely part, and the sexual reproduction we are more familiar with is another part.
