The document describes two key processes of evolution: mutation and migration. Mutation refers to changes in DNA that can impact an organism's traits positively, negatively, or neutrally, while migration, or gene flow, involves the movement of genetic material between populations, introducing new genetic variations. Both processes contribute significantly to the diversity of life and the evolution of species.

1. describe two processes by which evolution can occur.
explain why
Solution
There are plenty of processes are present, which leads to evolution. for example: Mutation,
migration, genetic drift, Selection (Natural and artificial) etc.
1. Mutation is the change in the sequence in DNA (herdiatery material of life). An organism's
DNA affects how it looks, how it behaves, and its physiology — all aspects of its life. So a
change in an organism's DNA can cause changes in all aspects of its life. it can be beneficial,
neutral, or harmful for the organism.
2. Migration, also known as gene flow, is any movement of individual, that carry genetic
material from one population to other. For example: pollen being blown to a destination or
people migrates to new cities. If gene versions are carried to a population where those gene
versions previously did not exist, gene flow can be a very important source of genetic variation.
