However, he doesn't believe in evolution and he thinks this is a good argument against it.
It isn't. It is based on a strawman which is easily refuted. In fact, I left a comment explaining why.
Theres a bit of confusion in my comment because Professor Dendy (biologist) has two blogs, which seem to have much the same content (other one here). I left a comment on this version of the story first (currently awaiting moderation) and then confused myself when I came across the story by other means. So to avoid confusion, I'll just repost my reply here, but do check out Professor Dendy's blog for some weapons-grade stupid.
There are several misconceptions here. I’ll skip over the ‘pond scum’ comment as a gross oversimplification and head straight to the following:
“If man is the latest and greatest species evolved”
This is not a claim of the theory of evolution. It doesn’t claim that Homo sapiens is either the latest or objectively the greatest species. Many species evolved later than humans. Many are better at lots of things than humans are. It’s hard to believe that anyone who understood the theory of evolution would claim that humans are ‘greater’ than other organisms. Just better at some things, worse at others.
In fact, the statement seems to reveal a fundamental but common misunderstanding of evolution: the assumption that there is some kind of progression over time which inevitably leads to mankind, with that species somehow at the ‘top’ of the evolutionary heap.
This is not the case. There is no direction in evolution, except in the trivial sense that modern organisms are necessarily more complex than the first ones because there was only one direction to go in; and tend to be more complex than earlier ones because evolution works by tinkering with existing organisms rather than starting from scratch each time.
Let me say that again: the theory of evolution categorically does NOT state that Homo sapiens is either the latest or greatest species.
Given that your entire point rests on this claim, I think we can safely ignore it. However, there are some more misconceptions to deal with:
“Isn’t the whole premise of Evolution that new species are better suited than the species from which they evolved? ”
Not at all. It is not true to say that later species are ‘more evolved’ or ‘better adapted’ than earlier ones. Better adapted to what? Humans are adapted to a different environment to the one our common anscestors with chimps were adapted to. This doesn’t make us more evolved or better adapted, just adapted to different things. Indeed, since we share a common anscestor with chimps, we are necessarily just as ‘evolved’ as they are and it’s likely that we are similarly well adapted to our environment (if not a little worse) than chimps are to theirs.
Besides, just because we find violent behaviour abhorrent, that doesn’t mean it is mal-adaptive. I’m not arguing that such behaviour is adaptive in humans (in fact, it seems more likely to be at least partly a symptom of the fact that our current environment is quite different to the one we originally adapted to, due to the large population, close proximity in cities, technology etc.) I’m just saying that the fact that we dislike some behaviour doesn’t necessarily mean that it is mal-adaptive, which you seem to assume.
Finally, you are aware that humans did not evolve from any of the other animals you mention, such as dogs, squirrels, canaries….right? In fact, we share a common anscestor with each of those animals and in almost every case, no modern animal is descended from any other modern animal.
I dread to think what Professor Dendy (biologist) is teaching his students about evolution. It's clear that he (presumably willfully) doesn't understand the first thing about it and has dismissed it without bothering to try. I'm not saying that Professor Dendy (biologist) is misleading his students about evolution, but if he is, then he is shortchanging their education and that ought to be a criminal offence.
By the way, I stumbled across Professor Dendy (biologist) when he left an idiotic comment (and then several more) on this Pharyngula post (just search for "professor dendy").
It's worth having a look at those comments and then looking at what he wrote about it on his own blog here.
Note that he didn't link to pharyngula or the comments, presumably so that his readers couldn't check what was actually said. That's not very honest, is it, Professor Dendy (liar)?
