Darwin`s theory - no stranger to controversy? (factsheet)
... How can you tell when a new species emerges from an old one? The scientist’s answer is that when two individuals can no longer mate and produce fertile offspring, then they are different species. Reproductive isolation of populations is essential for new species to develop. This isolation can be bas ...
