is that life forms most active in exchanging genes are supposedly the most primitive (such as bacteria). We would expect, if the basis of evolution was the exchange of genes, then those life forms most active in exchanging genes would evolve faster. Bacteria are by far the most active known | is that life forms most active in exchanging genes are supposedly the most primitive (such as bacteria).
