Development of Evolutionary Thought Flashcards
They pioneered some of the earliest theories on evolution
Georges Cuvier, Jean-Baptiste Lamarack, and Charles Darwin
This French zoologist and paleontologist, provided some of the earliest evidence showing that there were organisms that have existed before which no longer existed during this time.
Catastrophism by George Cuvier
His theory of inheritance of acquired trait posits that the environment affects the evolution of organisms.
Inheritance of Acquired Trait by Jean-Baptiste Lamarck (1744 - 1829)
Lamarck’s believed that there was a liquid component in an organisms body which he called
fluida
an English naturalist, geologist, and biologist.
is regarded as the father of evolution.
Theory of Evolution by Natural Selection -
Charles Darwin
He published On the Origin of Species detailing evidences for the theory of evolution by natural selection.
Charles Darwin
credited for their theory of evolution by natural selection
Charles Darwin and Alfred Wallace
Four Basic Principles of Natural Selection
- Variation
- Heritability
- Overproduction
- Reproduction Advantage
states that some traits allow individuals to gain more advantage in terms of fitness
Reproduction Advantage
states that organisms can produce more individuals than can be supported by the environment
Overproduction
states that variation in traits of individuals may be passed on to their offspring
Heritability
were done by breeders to produce individual organisms bearing traits that are advantageous in terms of the purpose of the breeders
Selective breeding or artificial selection
Individuals differ from one another
Variation
refers to the traits that increase the degree of adaptation of an individual to its environment.
Adaptive trait or evolutionary adaptation
defined as the degree of adaptation of an individual to its environment which is passed onto future generations.
