Does evolution teach that it created organisms that get together and one of them gets pregnant and bears a liter of little infant organisms suckling off the mother?
It can't, doesn't and won't! People who imply that it encompasses the creation of reproduction in living organism, aren't familiar with the lack of available evidence. Without evidence, one is forced to consider these implications a philosophy. Therein lies the problem.
The evidence reveals a commonality of programming in the DNA of living organisms. The evidence reveals that mutations can alter an organism in a horizontal or descending manner, but has not revealed mutations that increase complexity.
Nature is eroding the DNA of humans and the animal kingdom. This is why we see extinctions and not blossoming new forms of life. The evidence shows a tremendous decrease in the number of kinds of animals, and not a single new one. Heck, scientists can't even force a creature to become more complex than it's DNA is already preprogrammed for.
