Answer 1

natural selection and common descent are the 2 ideas Darwin used to explain evolution

Answer 2

Answer:

The correct answer would be natural selection and common descent.

Natural selection refers to the natural phenomenon by which a population evolves due to the presence of differential reproduction.

In evolutionary biology, the common descent describes how a group of organisms share a common ancestor.

Darwin also explained that the organisms evolve from a common ancestor as a result of natural selection.  

In different habitats or environment, organisms adapted differently as a result of natural selection and evolved in different species.
