Natural Selection

Evolution Means?

Evolution - Change in the genetic composition of a population during successive generations, as a result of natural selection acting on the genetic variation among individuals, and resulting in the development of new species.

the trace or remains of an organism that lived long ago, most commonly preserved in sedimentary rock

Fossil Means?

The actual or hypothetical organism from which later organisms evolved.

Extinction Means?

Dying out of species or population.

A relatively sudden, global decrease in the diversity of life-forms on Earth.

Mutation?

A relatively sudden, global decrease in the diversity of life-forms on Earth.

The act or process of being altered or changed.

Mold Means?

Fossil formed when an organism buried in sediment dissolves, leaving a hollow area

fossil that is a copy of the organism’s shape.

Cast?

Fitness?

To work out

Fitness - The extent to which an organism is adapted to or able to produce offspring in a particular environment.

Realative Dating?

Dating Someone that is your realative friend.

The proper chronological placement of a feature, object, or happening in the geologic time scale without reference to its absolute age.

Phylogeny?

- A dating method that utilizes the radioactive decay of certain long-lived, naturally occurring parent isotopes to stable daughter isotopes.

The evolutionary development and history of a species or higher taxonomic grouping of organisms.

Ancestor?

The actual or hypothetical organism from which later organisms evolved.

The act or process of being altered or changed.

Mass Extinction Means?

- A relatively sudden, global decrease in the diversity of life-forms on Earth.

Dying out of species or population.

- The adaptive evolution of superficially similar structures, such as the wings of birds and insects, in unrelated species subjected to similar environments.

Two things pressing together.

Gradualism

To Gradute

The view that speciation proceeds by imperceptibly small, cumulative steps over long periods of time rather than by abrupt, major changes.

Geographic Speciation

Social Studies

Evolution of two or more species from a single species following geographic isolation.

Coevolution

The evolution of two or more interdependent species, each adapting to changes in the other.

Two evolution

Acquired Trait

- a trait that is developed in an organism’s lifetime and is thus not inherited by its offspring. For example, humans gain knowledge over their lifetime, but they don't pass it onto their children.

- The evolution of two or more interdependent species, each adapting to changes in the other.

Natural Selection

The process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals do; a theory to explain the mechanism of evolution

Speciation

The evolutionary formation of new biological species, usually by the division of a single species into two or more genetically distinct ones.

The proper chronological placement of a feature, object, or happening in the geologic time scale without reference to its absolute age.

Geo

Evolution of two or more species from a single species following geographic isolation.

- When two species move away from the traits that they share with a common ancestor as they adapt to their own environments, the result is called divergent evolution.
