“Skunks may mate in the winter and the young are born in the spring. But sometimes they will mate in summer or autumn, triggering a most unusual event. The fertilized egg floats freely for several weeks, (or even as long as 180–200 days in the spotted skunk) and then implants on the uterus. This complicated process, known as delayed implantation, allows the animals to mate in summer or autumn and still bear young in the spring when food is plentiful and the conditions for growth and survival are optimum. This amazing form of reproduction is also known to occur in other members of the skunk family, as well as in bears and in the fallow deer. Four to seven young are born in mid–May and they are blind with fine hair. They are weaned in six to seven weeks and though their scent isn’t very potent, the function is already well developed.2”
This speaks to me of engineered/planned design – not evolution.
