My lengthy post 122 was in response to the question as to whether anyone would be able to explain the molecular basis of evolution. I thought it might be helpful to explain things a bit, and I thought it would be interesting to mention the Mendel/Darwin issue from the early 20th century.

There certainly is work to be done on the problem of speciation. My colleague I mentioned works on certain issues in the problem of speciation: he studies sympatric speciation, where new species form in the same ecological system from a parent species. (This is therefore different than allopatric speciation, where a species finds itself occupying different ecological systems, and speciation occurs when one of the ecological systems changes over time and the population in that system changes with it. If I'm not garbling this. What's interesting is that there are few examples of sympatric evolution.)

Yes. This kind of thing. Lots of issues remain about details of mechanism and what scenarios are most common, etc.
