It's not just horizontal gene transfer that can obscure evolutionary history. Scientists have found bacteria recycling fragmented DNA from long-dead organisms. The impact on evolutionary theory could be substantial.
Good scientific approaches should converge on the truth. In secular origin-of-life studies, theories run off in all directions, often crashing into one another.
On the 100th anniversary of his death, Alfred Russell Wallace is getting a smattering of attention, but not nearly what Darwin gets every day. Perhaps it's because the co-discoverer of natural selection believed in intelligent design.
