Please help!!!! Grizzly bears and polar bears are very closely related, so much so that they can reproduce to form hybrid offspring. Use your understanding of natural selection to describe how polar bears became a separate classification from the grizzly.

Scientists believe that at first these bears scavenged seal carcasses that had washed ashore, and gradually began to hunt the seals by waiting at the water's edge as the seals surfaced to breathe. This is believed to be an important step in the evolution of a new bear species, the polar bear

Over time the new polar bears were used to the cold climate and learnt how to fish, they then separated from the grizzly bears, they developed new creatures which would help them survive in one of the most dangerous climate.

Polar bears become separate classification from the grizzly by the natural selection known as divergent and adaptive evolutionary change.

Polar bears and grizzly bears are considered as closed to one another so they can interbreed. They both diverged from one another due to the harsh climate of the Arctic and the ecology of the region.

  • The changes that took place are camouflaging and pigment-free fur-coat that helped them in order to adapt to the different climates.
  • The genetic mutation leads to such Adaptive changes when the polar bears migrated northwards.
  • The populations living in different climates undergo natural selection that is divergent natural selection and the adaptive evolutionary changes that result in different species.
