Branching Descent is one of the two key concepts given by Darwin to explain his Theory of Evolution.

It is defined as a process by which new species originate from a single common descent ( i.e. that species).

We can explain this by taking an example of two organisms that are originated from a single common ancestor( or parent). If one ( may be both) of the new organisms formed becomes a lot different from each other and get adopted to a particular kind of environment, then it results in the formation of new species.

The following digram shows Branching Descent:

Species 1 produces two new organisms, one of the two becomes adopted forms a new species named as Species 2. This process is repeated by different generations as Species 3 and 4 is formed by the adaptation of any organism of Species 2. Species 4 and 5 are produced by Species 4 and so on.
