Macroevolution or microevolution?

Two types of rabbits live in a snowy area, brown rabbits and white rabbits. Soon a group of foxes move into the area and hunt for rabbits. Brown rabbits are much easier to spot than white rabbits, because white rabbits can camouflage into their environment. White fur is more advantageous in this scenario, so this trait will be more prevalent in the future population.

Macroevolution or microevolution? The three major bears all share a common ancestor. Due to multiple different factors, there are now three major species of bear, the grizzly, the black bear, and the polar bear. As the bears split into different areas and lifestyles, they evolved different and unique traits. The larger grizzly and polar bears are more powerful than the black bear, to take down bigger prey such as seals and moose. The black bear evolved to be an omnivore and to be able to climb trees, allowing it to be more versatile than the other bears
