Yes, it is true that evolution is a theory, which is a well substantiated explanation for observable facts.
Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction.
Different characteristics tend to exist within any given population as a result of mutation, genetic recombination and other sources of genetic variation.
Evolution occurs when evolutionary processes such as natural selection (including sexual selection) and genetic drift act on this variation, resulting in certain characteristics becoming more common or rare within a population.
The evolutionary pressures that determine whether a characteristic would be common or rare within a population constantly change, resulting in a change in heritable characteristics arising over successive generations. It is this process of evolution that has given rise to biodiversity at every level of biological organisation, including the levels of species, individual organisms and molecules.

Arboreal
Explanation:
Arboreal Definition:
Arbor is a Latin word meaning “tree”. Thus, arboreal means “related to or pertaining to trees”. The other similar words (synonyms) include arborous, arboraceous, arborary. Arbiform is the word used for expressing the term “resembling a tree”
Arboreal Animals
Arboreal animals : are those animals that spend most of their life on trees. They feed, travel, play, and sleep on trees. They prefer to grow their young ones on the trees, which is a difficult task because the newborns are always prone to fall on the ground from height. However, they have adapted themselves in such a manner that these animals can now easily live on such heights. Examples of such animals include chameleons, lizards, green tree pythons, tree snails, koalas, squirrels, cats, monkeys, parrots, sloths, and a variety of insects. Leopards and goats are also considered arboreal because of their excellent ability to climb the trees. Leopards can carry their kills to the top of trees to avoid other predators and scavengers.
a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
