Genetic changes include mutations, which are caused by damage or replication errors in organisms' DNA.

In this way, traits that result in organisms being better adapted to their living conditions become more common in descendant populations.

All individuals have hereditary material in the form of genes received from their parents, which they pass on to any offspring.

Among offspring there are variations of genes due to the introduction of new genes via random changes called mutations or via reshuffling of existing genes during sexual reproduction.

Microbial mat fossils in 3.48 billion-year-old sandstone have been found in Western Australia.

Based on the similarities between all present-day organisms, all life on Earth is assumed to have originated through common descent from a last universal ancestor from which all known species have diverged through the process of evolution.

For the population to remain the same size year after year, there must be an equilibrium, or balance between the population size and available resources.

Since organisms produce more offspring than their environment can support, not all individuals can survive out of each generation.

In addition, Gregor Mendel's work with plants helped to explain the hereditary patterns of genetics.
