Question

A new species was discovered, but only individual of the species that survive are the ones with a specific trait. This process is known as?

Answer 1

This process is known as natural selection.

This is a theory of evolution attributed to Charles Darwin in his 1859 book On the Origin of Species.

Natural selection means that organisms with a specific trait which makes them adapt better to their environment are more likely to survive and reproduce among themselves. The new generations therefore have these genetic qualities too, whereas the previous generations which did not have the trait die out.
