| Quote (N.Wells @ Sep. 08 2015,13:33) | According to evolutionary theory, species are expected to be groups that transition across their boundaries. In reality, species are found at all stages of transition, from well defined and isolated through freely hybridizing when the opportunity arises. Beyond that, we know that there are many potential routes and processes involved in speciation, so groups exist that can be defined as species by some definitions but not by others. A complex reality leads to complex semantics. Not surprisingly, this means that there are problems in coming up with sharp dividing lines about what is and what is not a species.
The ability of religious blinders to make people oblivious to the obvious is mind-blowing. |
