Inheritance  Individuals pass some of their genetic material to their offspring; parents pass on their traits to their offspring
Selection Some individuals have inherited character (genes) that allows them to better survive or produce more offspring. These offspring, in turn, are more likely to survive and create offspring of their own. As a result, their genes become more common in the entire population; some variants reproduce more than others.
Time Over time, selection results in changes in species. These changes may take days, or decades, or millions of years to occur; successful variations accumulate over time.

The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution.

An organism's DNA affects how it looks, how it behaves, and its physiology. So a change in an organism's DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation.

Gene flow includes lots of different kinds of events, such as pollen being blown to a new destination or people moving to new cities or countries. 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.

Types of evolution; a)divergent, b)convergent, and c)parallel.

Sexual selection acts on an organism's ability to obtain or successfully copulate with a mate.
Selection makes many organisms go to extreme lengths for sex: peacocks maintain elaborate tails, elephant seals fight over territories, fruit flies perform dances, and some species deliver persuasive gifts. Going to even more extreme lengths, the male red back spider literally flings itself into the jaws of death in order to mate successfully.
Sexual selection is often powerful enough to produce features that are harmful to the individual's survival. For example, extravagant and colorful tail feathers or fins are likely to attract predators as well as interested members of the opposite sex.

In other words, it's when very different animals have bones that appear very similar in form or function and seem to be related.

These included the muscles of the ear, wisdom teeth, the appendix, the tail bone, body hair, and the semilunar fold in the corner of the eye.

The field of molecular evolution uses principles of evolutionary biology
and population genetics to explain patterns in these changes. Major topics in molecular evolution concern the rates and impacts of single nucleotide changes, neutral evolution vs. natural selection, origins of new genes, the genetic nature of complex traits, the genetic basis of speciation, evolution of development, and ways that evolutionary forces influence genomic and phenotypic  changes.

Anatomical characteristics such as the rounded head and skeletal structure suggest that all the 37 recognised species within the Felidae family evolved from a common ancestor, probably living in Asia around 10-12 million years ago. There has been a rapid expansion and diversity of the Felidae family during the past 10 to 11 million years and by 3 million years ago there was a wide variety of cats populating all regions of the earth except the Arctic, Antarctic and Australia. The rise and fall of sea levels over many millennia helped both to create conditions where Felidae species could migrate and occupy other geographical locations (when sea levels were low) and isolate the development of species (when sea levels were high). The widespread migration of ancestral cats was probably made easier by their natural behaviour to disperse and seek their own territory, and also the need to follow the prey species they hunted on.
