Evolution Intro Vocabulary

What is evolution?

• the formation of new and distinct species in the course of evolution.

• the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.

• an organism's ability to survive and reproduce in a particular environment.

• 
  the fact or process of a species, family, or other group of animals or plants becoming extinct.

what is artificial selection?

• the process through which populations of living organisms adapt and change

• a change or the process of change by which an organism or species becomes better suited to its environment

• the identification by humans of desirable traits in plants and animals, and the steps taken to enhance and perpetuate those traits

What is fitness?

• the formation of new and distinct species in the course of evolution.

• the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.

• 
  an organism's ability to survive and reproduce in a particular environment.

• 
  the fact or process of a species, family, or other group of animals or plants becoming extinct.

What is extinction?

• the formation of new and distinct species in the course of evolution.

• the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.

• an organism's ability to survive and reproduce in a particular environment.

• 
  the fact or process of a species, family, or other group of animals or plants becoming extinct.

What is speciation?

• the formation of new and distinct species in the course of evolution.

• 
  the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.

• an organism's ability to survive and reproduce in a particular environment.

• the fact or process of a species, family, or other group of animals or plants becoming extinct.

What is a gene?

• a unit of heredity which is transferred from a parent to offspring and is held to determine some characteristic of the offspring.

• the process whereby organisms better adapted to their environment tend to survive and produce more offspring.

• an organism's ability to survive and reproduce in a particular environment.

• the fact or process of a species, family, or other group of animals or plants becoming extinct.

What is natural selection?

• 
  the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin

What is a species?

• 
  a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding.

• a group of living organisms who cannot exchange genes or reproduce

• an organism's ability to survive and reproduce in a particular environment.

what is a cladogram?

• A diagram representing a tree, used to illustrate hierarchical relationships.

• A branching diagram showing the evolutionary relationships among a group of species

• 1. A phylogenetic tree with branch lengths proportional to the amount of character change.
