A colleague of mine says humans have caused the extinction of "millions of species," but that strikes me as hyperbole. Can you point me to any credible sources on this question? [more inside]
I'm beginning a project that looks partly at biological classification, primarily in western science. I have no background in this, and so I'm digging around. I'm interested to know more about the current rules for nomenclature, and also to know more about historical, philosophical, sociological, knowledge practice, ethnographic, anthropological, science technology and society (STS), sociotechnical, etc., approaches to the study of biological classification. I'll take monographs, articles, papers, web sites, etc. I have access to a university library. What are some good sources that can introduce me to this? Many thanks!

Half-remembered board game ID question: In the mid-'90s, my family was visiting some friends who owned a strange board game involving evolution, species, a hexagonal grid, and lots and lots of dice. What was it? [more inside]
Asking for a friend - can anyone tell me exactly what type of jellyfish this is?
Is there a website out there where I can enter the names of two species and be given the approximate date when their last common ancestor lived? Bonus points if it tells me what sort of species this ancestor probably was, and for showing me the part of the tree of life relating to these species. Thanks!

I once read a claim that the Chinese government had funded "research" whose aim was to prove that Han Chinese are a different species to other humans. It was a physical book, not online. What might it have been? And incidentally, is the claim true?

Assume you had a list of different animal species, and you wanted to order it from most intelligent species to least. (1) What measure of intelligence would you use to compare different species--average number of neurons, for example, or ability to solve certain kinds of tests? Or something else entirely? (2) Can you give some examples of how some common farm, food, or pet animals might rank on the list? [more inside]

Is there a limit to scientific advancement? If there is only a certain number of elements to the universe, will there reach a technology plateau? [more inside]
It's easy to tell when a species has gone extinct. How do you tell when a new species has evolved? Are there any criteria besides not being able to mate with the former species?
Can fish interbreed like dogs? My SO and I have been talking about dogs lately so the mixed-breed thing has been a regular topic of conversation. Last night we were at a Thai restaurant with a large fish tank and some gigantic fish. Too big for the tank, in my opinion. And that got me to wondering....can different kinds of fish, genetically speaking, be bred with each other? Even if they wouldn't do it on their own (mating rituals, etc.), could they do it with a scientists help?
