What are the observable facts about living organisms that establish evolution by natural selection?
What are the observable facts about living organisms that establish evolution by natural selection?
- Few offspring are produced; traits do not vary among individuals; different traits confer the same rates of survival and reproduction; traits cannot be passed from generation to generation
- More offspring are often produced than can possibly survive; traits do not vary among individuals; different traits confer the same rates of survival and reproduction; traits can be passed from generation to generation
- All offspring survive; traits do not vary among individuals; all traits confer the same rates of survival and reproduction; traits cannot be passed from generation to generation
- More offspring are often produced than can possibly survive; traits vary among individuals; different traits confer different rates of survival and reproduction; traits can be passed from generation to generation (correct)
