Michael Behe on extreme devolution: “Gnawing off a leg”

Behe: Like tusks to elephants, the proteins are presumably useful to the parasite, other things being equal. But when the environment changes and the proteins become a net drawback, the quickest evolutionary solution is to get rid of them. That’s an interesting fact of biology and can be medically important. However, it’s important to note that it’s just one more example of devolution — the beneficial loss of genetic information.

Grand Darwinian experiment with 10,000 generations of yeast proves that Mike Behe is right

If the authors could have predicted adaptation through loss-of-function mutations, why didn’t they let high school textbook authors and pop science presenters in on the secret?: Michael Behe is right: Darwin devolves. Evolution is mostly about devolution. Does that maybe make sense in a universe where entropy is growing? But where does it leave Darwin? At the bus stop after the last bus has left?

An animal has been discovered that does not need oxygen to live

Devolution, of which this is an example, may be more common than we suppose and will probably have precisely the effect of creating “exceptions” like this. Note that we are told, “they likely steal energy from their host using some type of proteins.” It makes sense that many devolved creatures are parasites. They can afford to throw away equipment if they are using the host’s toolbox anyway.
