Evolutionary Adaptations

Front

A genotype of inherited traits that enhance an individuals ability to survive and reproduce in a particular movement.

Back

convergent evolution

Front

Process by which unrelated organisms independently evolve similarities when adapting to similar environments.

Back

Molecular homologies

Front

similar molecular composition of proteins, DNA

Back

Taxonomy

Front

The scientific study of how living things are classified. Created by Linnaeus.

Back

Major points of The Origin of Species

Front

Evolutionary change is based on the interactions between populations and their environment which results in adaptations (inherited characteristics) to increase fitness. 1. Adaptations 2. Overproduction

Back

Vestigial Structures

Front

A structure that is present in an organism but no longer serves its original purpose

Back

Lamarck

Front

Published Theory of Evolution in 1809. 1. Told of Inheritance of Acquired Strengths. 2. Use and Disuse

Back

Charles Darwin

Front

Origin of Species. Descent with modification.

Back

Biogeography

Front

study of the distribution of organisms around the world

Back

Homologous Structures

Front

Have similar structures from common ancestors, but serve different functions. Ex: human arm, bat wing

Back

Alfred Wallace

Front

Published his own theory of evolution by natural selection about the same time as Charles Darwin

Back

Analogous Structures

Front

similarities among unrelated species that result from convergent evolution. Ex: Wings for flying

Back

Voyage of the Beagle

Front

1831 trip around the world- mainly Galapagos Islands.

Back

Natural Selection

Front

A process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits.

Back

Linnaeus

Front

founder of taxonomy; binomial nomenclature

Back

Artificial Selection

Front

Breeding organisms with specific traits in order to produce offspring with identical traits.

Back

Evolution

Front

Change over time in the genetic composition of a population.

Back

Endemic Species

Front

Species that are native to and found only within a limited geographic area.

Back

embryonic homologies

Front

Comparison of early stages of animal development reveals many anatomical homologies in embryos that are not visible in adult organisms
