→Evolution
:4. Evolution. By the processes of [[natural selection]] and [[genetic drift]], the inherited traits of a population will change from generation to generation, sometimes leading to the arising of new, distinct populations from the 'parent population'. This is often included with [[common descent]], but in most fields of biology the latter does not arise; however, evolutionary theory itself is invaluable in agriculture, study of disease and research on genetics.

Let's stick to facts and use terms everyone understands. Were you referring to [[mutation]]? I've heard that this has been observed in laboratories, and that there is a scientific theory about it.

As for [[common descent]], I'm unaware of any proof having been offered for this conjecture. Let's make a bright distinction between scientific theories (which have been proved or are at least "falsifiable") and conjecture (see also [[Pseudoscience]]). --[[User:Ed Poor|Ed Poor]] 10:29, 19 May 2007 (EDT)

:::Would the section be OK if the reference to common descent were omitted? Like I said - it's usually lumped in with evolution in the common mind, but most biology only uses evolution (with common descent a question of paleontology and such).--[[User:M|M]] 17:19, 19 May 2007 (EDT)
