The race issue

We tend to notice the visible differences between groups of humans easily, probably because our brains are geared to focus intensively on our own species. However, your doubts could just as well have been caused by the differences between groups in other species, which is often more radical.Take the African and Asian lions, for example, or Tigers (including the Siberian) or the leopards (including the Snow Leopard) and can you see each species descending from a pair that was on the ark 4300 years ago?Geneticists would laugh at the idea, so you are right to have doubts about creationism.Then add the complication that lions, tigers and leopards can all produce (usually sterile) offspring in captivity, and it looks as though the evolutionist's explanation, that they all descend from a common ancestral species, might have a lot going for it.In humans, I think I'm right in saying, the diversity has come about since we went through a "bottle-neck" of about 5 to 7,000 people about 75,000 years ago, and it's very insignificant, as that's yesterday in evolutionary terms.Welcome to EvC.
