I'v got a question. A central theme of evolution is that today's species are a culmination of natural selections of many different species. Has cross-species evolution ever been observed outside of the fossil record?

What do you mean? Evolution is not a "jumpy" process, it's a smooth and gradual one.

I think culorut's mum bred with a pig. Is that what you mean?

Has anyone observed, for example, a dog whose offspring is no longer a dog? Or is it like, a chihuahua, whose ancestor is a wolf (i think), can't mate with the original ancestor, a wolf. By the way, can a chihuahua and wolf breed?

The amount of genetic mutation that would be required for a dog to give birth to offspring that - in a single generation - was genetically distinct enough to be classified as a separate species from it's mother is, in practice, prohibitively impossible. A fetus with that degree of damage to its DNA won't get past the earliest stages of development.

Lupine and canine are classified as distinct species because in a natural environment they will not choose to breed. Whether they are capable of it or not is something I'm not sure I really want to think about.

Life started as an Amino Acid and now you are a piece of shit. GET IT?

Well Wolves and Dogs can be mixed and certainly there are half dog half wolves. A member of my family has one.

As far as a chihuahua, I don't know, I'm babysitting one this weekend though... I'll find him a nice werewolf.
