The environmentalists are huffing and puffing about Polar Bears being threatened and argue that they should be on the protected list.
Why suddenly are these people so against evolution ?
Somewhere during the mid-Pleistocene period, a number of grizzly bears (Ursos arctos) became isolated by glaciers. Many probably perished on the ice; however, not all disappeared, some survived. Every grizzly litter varies in coat thickness, coat color etc., which imparts a slight evolutionary advantage to some individuals of each litter. These successful individuals underwent a series of evolutionary changes in order to survive (survival of the fittest). Nowdays, polar bears are adapted to their harsh northern environment.
Today, we find that the grizzly and polar bears are coming full circle. Yes, the Kodiak and Polar bears are getting it done !
Well I Say !
Welcome, ... Welcome ursid hybrid to modern day's Earth !
Changes are normal part of evolution as it has occurred for the past 4.5 Billion years on the 3rd rock from the sun. Let it Be !
