trans time ...

... in the 1970's while studying unicellular organism and their ability to sequence genes, which should have been a scientific way of proving darwin’s tree of life ...
darwin assumed that organisms passed their genes to their offspring. Instead, what was seen was that some bacteria and some single-celled microorganisms swapped genes across huge distances.
lateral transfer of genes was not the way the tree of life was to be, evolutionary biology had the axe ready to cut down the tree of life further. fungi, amoeba, algae are themselves a product of fusion ...
unicellular organisms make for at least 90% of all species on earth and 80% of them show lateral gene transfer. lateral transfers are seen in plants and animals too, about 14% of all living plant species and about 10% of all animals have been found to be “products of fusion of two separate lineages.”
“downgrading the tree of life doesn’t mean that the theory of evolution is wrong, just that evolution is not as tidy as we would like to believe.”
