obviously it takes thousands of years to happen, but does it? maybe it just takes thousands of genarations, in which case could they not get something with a very short life span like a fruit fly, control it enviroment and see what happens?

Why hasn't the skin of the white people who live in Australia become any darker yet. I mean, some of their families have been there for a couple hundred years now and they still get sunburned worse than a white British person who goes to Spain on holiday. If this process was to happen, how long would it take?

I wonder if any one could confirm or not. In the parietal cell there appears to be more mitochondria then in the goblet cell. Does this indicate that the release of HCI and intrinsic factor require more energy?? also would the transport of intrinsic factor need to cross the membrane via the protein pump??
Thanks.

Why do we not have "half-monkeys" walking around? Why has everyone COMPLETELY evolved if they are not a monkey, yet there are still monkeys?

I am not religious and believe more in science, but I just wonder these things.

The record of primate evolution remains frustratingly incomplete and subject to debate. For certain periods of time over large areas there are no fossils known at all. At other times, in other places, there is an abundance of fossils. What are three significant gaps and/or debates involving the fossil evidence, and what kind of new fossil discovery would fill a significant gap or resolve a major debate in each case. Describe these hypothetical discoveries for each of the three cases.
