One of the wonderful things about science is that science is open to new ideas and new facts. What do I find fascinating about HGT? That for most of history we didn't believe that this kind of genetic transfer was possible. How does it 'destroy Darwin'? Darwin postulated on 'the origin of the species' - that modern species all descend from earlier ancestor species. Darwin of course didn't know about genetics or genes when he came up with his theory. What has happened in the last 150 years is that our knowledge about evolution has expanded as our knowledge of biology has expanded. The science- including genetics- still show for example that modern whale species descended from earlier whale species which in turn came from earlier land species. H.G.T. doesn't change any of that- but it does show there are additional ways that genes can transfer- which is fascinating and will need to be incorporated into any genetic research of any species.
