First Test Study Material Flashcards
The scientist who believed in natural selection and evolution
Charles Darwin
Scientist that used binomial nomenclature
Carolus Linnaeus
the evaluation of similar structures across a variety of species, using fossils and comparing them to extant (still in existence) species.
comparative anatomy
anatomical structures that functioned in an ancestor, but have lost most or all their function. Example: the internal useless leg bones in the glass lizard and the vestigial leg bones of whales.
vestigial structures
Scientist who use paleontology to prove evolution
Baron Georges Cuvier
the genetic change of a species over time
Evolution
He Propose the idea of inheritance of acquired characteristics but it was not true
Jean-Baptiste de Lamarck
What is inheritance of acquired characteristics
the idea that the environment can produce physical changes in an organism in its lifetime that are inheritable.
a geologist who proposed a theory of slow, uniform geological change. This contrasted with the belief in catastrophism.
Charles Lyell
he proposed that the sizes of human populations were limited only by quantity of resources, such as food, water, and shelter, available to support it. He also stated that famine, war, and epidemics happen when populations overstretch their limited resources.
Thomas Malthus
the study of geographic distribution of organisms throughout the world and can give hints to past geological events, such as continental drift, formation of islands from volcanos, and ecological change, such as river formation and glaciation.
Biogeography
Organisms exhibit variation that can be passed from one generation to the next – that is, they have inheritable variation.
• Organismscompeteforavailableresources.
• Individuals within a population differ in terms of their reproductive success.
• Organisms become adapted to conditions as the environment changes
Principles of natural selection
the reproductive success of an individual relative to other members of a population or if they’ve got pretty spots they get more females
Fitness
any evolved trait that helps an organism to be more suited to its environment.
Adaptation
Humans artificially modify traits in plants and animals for human benefit. This type of human-controlled
breeding to increase desired traits
artificial selection.
