You can only predict evolution if the environment remains relatively
constant. Technology is now changing the adaptive landscape at an enormous
rate. Another factor is that we are just beginning to learn how to
manipulate the genome directly.

Species aren't well defined through time. The normal definition is that
members of the same species must be able to interbreed, but there is a chain
of potentially interbreeding ancestors that connects a modern human to homo
erectus, ancestral apes, the earliest mammals, and even the ancestral fish.
However obviously a modern human couldn't interbreed with a Devonian
armoured fish.
