Darwin - Answer✔️✔️-A biologist who developed theory of evolution of species (1859).
He argued that all living species evolved into their present form through the ability to
adapt in a struggle for survival.
Charles Darwin published On the Origin of Species by Means of Natural Selection in
1859, which presented evidence for evolution
Dissent with Modification - Answer✔️✔️-Darwin's definition of evolution.
Favorable traits are passed down from generation to generation will organisms with
unfavorable traits die.
Natural Selection - Answer✔️✔️-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.
Individuals with certain inherited traits are more likely to survive environmental
pressures and reproduce than those that don't have those traits.
