never observed, an atheist believes in this as his substitute for the existence of God
'''Speciation''' is the process by which new species arise. Speciation occurs when gene-flow stops between two sub-populations due to geographic or behavioral isolation. During such isolation the gene pool of each sub-population reacts differently to the processes of [[natural selection]] and [[genetic drift]] and such evolve divergently. If this evolutionary divergence becomes great enough that crosses between individuals from different sub-populations can no longer produce viable offspring each sub-population is considered to be a new species and speciation is said to have occurred.
'''Speciation''' is a hypothetical process by which new species arise. In fact, speciation has never been observed directly or indirectly. An atheist believes in speciation regardless of the evidence, because it serves as his substitute for the existence of God.
Evolutionists, typically atheists, insist that speciation should occur when gene-flow stops between two sub-populations due to geographic or behavioral isolation. During such isolation the gene pool of each sub-population reacts differently to the processes of [[natural selection]] and [[genetic drift]] and such evolve divergently. If this evolutionary divergence becomes great enough that crosses between individuals from different sub-populations can no longer produce viable offspring each sub-population is considered to be a new species and speciation is said to have occurred.
