natural selection
The characteristics that all animals have is that they all have characteristics, they all have cells, and comes from another cell wich come from another cell and so on....
There are a great number of characteristics of animals. Animals must be able to eat and excrete waste as well as grow.

Outcrossing of individual animals of the same species that are unrelated or very distantly related (beyond the 5th generation) often creates hybrid vigor...where the offspring are healthier and more robust than either parent. This is often done when a group of individuals are so closely related that fertility or health diminish due to the higher concentration of the same alleles in the entire group. It can also be used to add desired characteristics into a breeding program. The disavantage of a complete outcross is that recessive characteristics are often masked in the F1 generation. Inbreeding of animals of the same species is done in an attempt to fix desireable characteristics in a group. The breeder using this technique must be careful to cull offspring with undesirable characteristics as well as examine whether the parent animals should be used for continued breeding. It is generally agreed that inbreeding within the 1st through 3rd generation should be followed by an outcross and/or the beginning of a linebreeding program.
Animals and humans are both in the animal kingdom. Characteristics that animals and humans share are emotions, thoughts, and physical similarities. For example, a humans and animals are social beings who form bonds with family, friends, and neighbors.
natural selection
thrive in; genetic characteristics
Charles Darwin observed that plants and animals reproduce to further their species. While some off spring may not survive, those that do are more suited to be prevailing environment and will pass those characteristics to the next generation.
two animals in an environment competing over a specific area
Considering those animals were adapted for that specific environment, I'd assume that they would just die out.
Based on similar characteristics, traits animals share get more and more specific until you can specify a specific kind of animal
Broadly speaking, animals survive through adaptation to the environment. There are hundreds of different animals that live in the Sahara desert, so it is difficult to give a more specific answer.
Plants and animals are physically well adapted for that area. Plants and animals that live in a specific biome share similar characteristics with other plants and animals in that biome throughout the world.
Animals live in diffrent habitats. Their habitat may be at a specific place or in a specific country or all around the world but its still their habitat their natural environment.
two animals in an environment competing over a specific area
Animals compete because they need to ensure their genes are passed on to the next generation. The animals with the best genes/adaptions are more likely to survive and successfully mate therefore passing their genes on. The process of which the strongest (or just best suited to the environment) genes survive on to the next generation is called natural selection.
