Evolution is the result of variation and natural selection. After a certain point, an offspring will have to have some pretty significant mutations (in addition to natural selection for certain already-present alleles) present in order to be of a different species than the population it was derived from, although this can take many (an understatement) generations. Supposing that an offspring was a different species than its parents, it would not be able to produce offspring that could produce offspring. Are there supposed to be two of these new species being born around the same time, or are mutations supposed to be gradual, with offspring continuously being compatible with the rest of the population (intermediary species)? Also, what are the chances that these mutations come out favorably (i.e., Down Syndrome), and does the amount of time given for evolution to occur take this into account? Again, just asking, not trying to disprove anything.
