::No, my answers are to the effect that these particular examples are not considered ''problems'' by biologists at all, they're simply unresolved issues with a number of competing plausible theories that continue to be tested. As for the gravity example, well, we know that gravity exists because we observe its effects, and we know that life originated (and the rough timescale) through observation of its effects, mainly fossils and living creatures. The precise method by which the origin of terrestrial occured is scientifically better understood than the precise method by which gravity occurs. And yes, there are people who [http://www.fortunecity.com/emachines/e11/86/gravity.html deny the existence of gravity].
