True or false, evolution happens when an individual organism starts changing itself to adapt to its environment. For example, an adult polar bear might start swimming more so it can handle the melting of the polar ice caps.

false, if it had a cub that could swim better due to longer legs or more buoyant bone structure, this could become a more common trait.

True, evolution happens due to changing individuals

maybe, if it chose to.

d)

I wish I had a pet penguin
