The religious would have us believe intelligent design... I don't wish to convert anyone, but I'll state what I learned. I raised & studied wolves & hybrids for 20 years. Started with white Siberian Wolf and white G. Shepherd mix. Recessive genes? I gradually increased wolf % in hybrids. A number of mutations * occurred! A few, in nature, might have led to new, survivable kinds. Others were degenerate. It's too much to go into here. My point is that it all appeared RANDOM! No intelligent design! Methinks evol.= random!
