Natural selection Flashcards
(18 cards)
A characteristic that improves an individual’s ability to survive and reproduce in a particular environment
adaption
A group of organisms that are closely related and can mate to produce fertile offspring
species
The process in which inherited characteristics within a population change over generations such that new species sometimes arise
evolution
the remains of physical evidence of an organism preserved by geological processes
fossil
A historical sequence of life indicated by fossils found in layers of the earth’s crust
fossil record
a genetically determine characteristic
trait
The human practice of breeding animals or plants that have certain desired characteristics
selective breeding
The process by which individuals that are better adapted to their environment survive and reproduce more successfully than the less well adapted individuals do a theory to explain the mechanism of evolution
natural selection
The period between the birth of one generation and the birth of the next generation
generation time
The formation of new species as a result of evolution
speciation
Any method of determining that weather and event or object is older or younger than other events are objects
relative dating
Any method of measuring the age of an event or object in years
absolute dating
The standard method used to divide the Earth long natural history into manageable parts
geologic time scale
Describes a species that has died out completely
extinct
the theory that explains how large pieces of Earth are most are called tectonic plates move and change shape
plate tectonics
A primate is any member of the biological order Primates, the group that contains all the species commonly related to the lemurs, monkeys, and apes, with the latter category including humans.
primate
Hominid – the group consisting of all modern and extinct Great Apes (that is, modern humans, chimpanzees, gorillas and orang-utans plus all their immediate ancestors).
hominid
the species to which all modern human beings belong. Homo sapiens is one of several species grouped into the genus Homo, but it is the only one that is not extinct. See also human evolution.
