Would larger species of animals, like lions or elephants, not be as subject to natural selection?

Question

It seems like natural selection mostly occurs with smaller species.

Answer 1

All species are subject to natural selection.

How did elephants get such big tusks/teeth?
Why do elephants make those too-low-to-hear rumbles?
Why aren't elephants covered with fur?

Why do lions sleep and lie around so much?
Why do lions give up so quickly when a prey animal is getting away from them?
Why are lions the right color to blend in with dry grasses?

And on and on and on.

I think that it's easier to see natural selection in smaller organisms because the generations pass by more quickly. Also, smaller organisms are more likely to be present in larger numbers, so we can see the variations more readily.

Answer 2

The answer above is correct. Because generation time is so much longer for such species, natural selection acts over a greater period of time. For bacteria, however, there are two factors that seem to accelerate selection: first, they have a rapid regeneration time; second, they are extremely sensitive to their environments, so any slight change immediately selects for the most fit individuals.
For natural selection, as with most laws in nature, have to be applied with reference to the species in question, not from our own point of view. Don't be species-centric!

Answer 3

Natural selection occurs with ALL species. It may not be apparent at first because larger species take more time than smaller species to reproduce.

Answer 4

Everything that has DNA is susceptible to naturally selection. Natural selection is a result of altered DNA, leading to a trait that may be beneficial to the organism within that particular environment.

Mammals don't reproduce often and their number of offspring are so small, the probablility for the genetic information to get mixed up is lower and thus not so obvious.

Answer 5

Because larger animals, like lions and elephants have longer life spans than animals, such as nymph flies or cane toads, the effects of natural selection are not as obvious to people.

Answer 6

people, relating to offspring, have shown themselves to be something yet altruistic. for the time of international conflict II, while the Germans placed an embargo in specific ecu countries, toddler and new child mortality sky rocketed as mothers and dads fed themselves and allowed their babies to starve. interior the animal international (no longer different phyla), mothers and dads will look after their offspring in an attempt to be sure that the discern's genes are handed on. besides the undeniable fact that, the mothers and dads do no longer sacrifice themselves. while the discern determines they can't shop their offspring with out sacrificing themselves, they enable the offspring strengthen right into a buffet.

Answer 7

I don't see why not. The standards for biggest and the baddest change with the change of the environment.

Answer 8

hmmm ask me later when you give birth to a child that is so physically and mentally defecient as to not be able to survive in the wild
