There are many different ways species change, but most of them can be described by the idea of natural selection.The theory of evolution through natural selection was the first scientific theory that put together evidence of change through time as well as a mechanism for how it happens.
The scientific theory of evolution by natural selection was proposed by Charles Darwin and Alfred Russel Wallace in the mid-19th century and was set out in detail in Darwin's book On the Origin of Species (1859).
