Seals and penguins both have streamlined body forms that allow them to move through water efficiently. this similarity in body shape is mostly likely the result of:

Convergent evolution

Seals and penguins both have streamlined body forms that allow them to move through water efficiently. This similarity in body shape is mostly likely the result of: convergent evolution .

Convergent evolution is the mechanism in which organisms of different species or lineage independently evolve similar traits such as adaptations, body shape, colors and organs. Convergent evolution produces corresponding structures that functions the same way but were not possessed by the last common ancestor of those species.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
