Summary

Horizontal gene transfer is increasingly described between bacteria and animals. Such transfers that are vertically inherited have the potential to influence the evolution of animals. One classic example is the transfer of DNA from mitochondria and chloroplasts to the nucleus after the acquisition of these organelles by eukaryotes. Even today, many of the described instances of bacteria-to-animal transfer occur as part of intimate relationships such as those of endosymbionts and their invertebrate hosts, particularly insects and nematodes, while numerous transfers are also found in asexual animals. Both of these observations are consistent with modern evolutionary theory, in particular the serial endosymbiotic theory and Muller’s ratchet. Although it is tempting to suggest that these particular lifestyles promote horizontal gene transfer, it is difficult to ascertain given the nonrandom sampling of animal genome sequencing projects and the lack of a systematic analysis of animal genomes for such transfers.

How’s Darwinism looking now, as the source of most variations over time in life forms?  And who predicted this?

Is this why Larry Moran says he is not a Darwinist, but a pluralist?

I’d sell my stock in that firm too, if I ever had any. But now I want him to explain what he includes and excludes in pluralist. If he agrees, the floor here is his, for a while.

One Response to Horizontal gene transfer from bacteria to animals

  1. If you read the summary that you post it says “Both of these observations are consistent with modern evolutionary theory, in particular the serial endosymbiotic theory and Muller’s ratchet.” The researchers plainly say this is consistent with modern evolutionary theory. And we have known about Horizontal gene transfer between viruses and non-viruses and plants and bacteria this is only a small step in biological understanding. Also in the blog you often say Darwinism or Darwinist now that is just completely wrong modern evolutionary theory has its foundations in Darwin’s theorys but many of his ideas have been proved incorrect since the 1860′s and many new things have been added. If someone today believed in Darwin’s theory of evolution without adding any of the changes that have accrued in the past 150 years thats like believing in Newtonian physics with the exclusion of Einsteinian mechanics.

    Also in Uprooting the Tree of Life by W. Ford Doolittle (Scientific American, February 2000, pp 90–95), Doolittle predicts horizontal gene transfer and discusses its effects on evolution and the idea of last common ancestor.
