Some force other than environmental conditions must be acting upon the males to produce so many species. Choice (d) is incorrect because it would be possible for this species to evolve over time. Over time, the genetic makeup of the two resulting populations becomes more and more different, until each population becomes a separate species.

Some populations are innately superior to others, because they have what it takes to prevail in those environments. It is believed that humans started to transfer information from tools to symbols and from symbols to letters from generation to generation. The most common mechanism for this is natural selection, in which individuals with beneficial heritable traits reproduce more than organisms without these traits, causing an increase in the frequency of the trait within the population. b.
