resources on species selection

What traits can a group of organisms possess that an individual cannot possess (e.g. a ratio of males to females)? To put it more generally: in reference to units of selection, can you cite any examples of a whole being greater than the sum of its parts (particularly the sum of its genes)? [more inside]

What website will give the last common ancestor of two species?

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!

How did sexual reproduction evolve?

How did we evolve separate genders? I assume it happened pretty early on, since most animals have a male and female, but wouldn't it have had to happen to lots of things at once for it to actually work?

How do evolutionary changes occur in biology? Is there some sort of "intelligence" that helps a species adapt, or does a species have to wait for a random mutation to occur that just happens to confer an advantage (a mutation that might never even happen)? For instance, how do bacteria become resistant? And are there different theories on evolutionary changes?
