what i fail to understand is why is cousin marriage today socially unaccepted when it was the norm throughout history? i used to somewhat advocate against it using the argument of gene pool diversity, etc… and now that argument doesn’t hold anymore.

Very nice article! Very enriching results. The secrets of evolution being revealed! It’s breath-taking how cells, and DNA have reached such complexity by simple “tricks”.
I strongly believe that in the coming few years, more would be discovered to explain to everyone how we are the ancestors of cells and how life began.
The research in Switzerland -with the atoms placed in vacuum supplied with electrical energy gave simple living organisms-… that’s a huge leap..

Genes evolve by various mechanisms, but all of them need a “random accident”… Apes evolved into humans, what will humans develop into in the future? If all these mechanisms continued to occur what would be the result of the evolution of the current genome? would it be beneficial, and would it be chosen by natural selection?
Millions of question about the past and future evolution trigger scientists minds and it seems they are working hard to find the answers…
Here’s how the father of evolution, Charles Darwin, centuries before the discovery of genes and mutations, came out with the idea of “mutations” or as he simply called them: “differences”…
“Whatever the cause may be of each slight difference in the offspring from their parents – and a cause for each must exist – it is in the steady accumulation, through natural selection, of such differences, when beneficial to the individual, that gives rise to all the more important modifications of structure, by which the innumerable beings on the face of this earth are enabled to struggle with each other, and the best adapted to survive”
As an answer to these claims, which time will prove right, a prominent scientist of Darwin’s era, Sir John Herschel wrote: “Darwin recognises an unknown cause of slight individual differences – but claims for ‘natural selection’ the character of a ‘sufficient theory’ in regard to the results of those differences”
This is another proof of the rightness of what Albert Einstein once said and firmly believed
in: “imagination is more important then knowledge”.
