Here a newsstory about horizontal gene transfer:
Compare with neodarwinism:
Since gene swapping by organisms causes genetic variation, does this contradict neodarwinism which claims genetic variation is caused by random mutations?
Horizontal gene transfer (HGT) is a cross-species form of genetic transfer. It occurs when the DNA from one species is introduced into another. The idea was ridiculed when first proposed more than 50 years ago, but the advent of drug-resistant bacteria and subsequent discoveries, including the identification of a specialized protein that bacteria use to swap genes, has led to wide acceptance in recent years.

Compare with neodarwinism:
Neo-Darwinism generally denotes the integration of Charles Darwin's theory of the evolution of species by natural selection, Gregor Mendel's theory of genetics as the basis for biological inheritance, random genetic mutation as the source of variation, and mathematical population genetics.
