- artificial selection
- process of breeding organisms with specific traits in order to produce offspring with those same traits.
- analogous structure
- structures that do not have a common evolutionary orgin but are similar in function.
- biogenesis
- The principle that living organisms develop only from other living organisms and not from nonliving matter.
- antigen
- foreign substance that stimulate an immune response in the body.
- antivenom
- is a biological product used in the treatment of venomous bites or stings. It is created by injecting a small amount of the targeted venom into an animal such as a horse, sheep, goat, or rabbit; the subject animal will suffer an immune response to the venom, producing antibodies against the venom's active molecule which can then be harvested from the animal's blood and used to treat envenomation in others.
- camouflage
- structural adaption that enables species to blend with their surroundings; allows a species to avoid detection by predators.
- coevolution
- The evolution of two or more interdependent species, each adapting to changes in the other. It occurs, for example, between predators and prey and between insects and the flowers that they pollinate.
- coelomates
- Possessing a coelom
- bioluminescence
- Emission of visible light by living organisms such as the firefly and various fish, fungi, and bacteria.
- acoelomates
- An animal that lacks a coelom. Acoelomates, which include the flatworm, fluke, tapeworm, and ribbon worm, exhibit bilateral symmetry and possess one internal space, the digestive cavity.
- autotrophic
- organisms that use energy from the sun or energy stored in chemical compounds to manufacture their own nutrients.
- arachnid
- Any of various arthropods of the class Arachnida, such as spiders, scorpions, mites, and ticks.
- aves
- A class of animals composed of the birds, which are warm-blooded, egg-laying vertebrates primarily adapted for flying.
- allelic frequency
- percentage of any allele in a population's gene pool.
- carnivore
- A flesh-eating animal.
- adaption
- An alteration or adjustment in structure or habits, often hereditary, by which a species or individual improves its condition in relationship to its environment.
- cephalothorax
- structure in some arthropods formed by the fusion of the head and thorax.
