I'm a sucker for these kinds of discussions. Evolution is way messier than you think it is, and evolutionary biologists get really heated about clades vs grades and so on and so forth. For fun, spend some time on the r/evolution and r/biology subreddits and you'll occasionally run into one of these heated debates. One of my favourites:

If you ever meet an evolutionary biologist at a party, ask them if apes are monkeys. I think the closest thing for a Web developer like myself would be casually dropping into conversation the comment that "an Englishman invented the Internet".
