Chapter 10.1 10.2 10.3 10.4 Flashcards
What are the species?
Is a group of organisms so similar to one another that they can reproduce and have offspring
Define evolution:
Is the process of biological change in which descendants come to differ from their ancestors
What is the theory of evolution that Buffon purposed?
He discussed important ideas of relationships among organisms, sources of biological variation, and the possibility of evolution.
What did Erasmus Darwin Purposed?
All living things were descended from a common ancestor. He explained more complex forms of life in less complex forms
What did Linnaeus proposed?
He proposed a new system of organization for classifying species.
What did Lamarck proposed?
He explained that changes in the environment cause an organism to change it’s behavior
What did Lamarck not proposed?
He did not proposed how traits were passed on to offspring and his explanation of how organisms evolve was flamed.
Are traces of organisms that lived in the past
Fossils
Explain what catastrophism is:
Earthquakes, floods, volcanic eruptions have often happened over Earth’s history. These events have changed and shaped landforms.
What is gradualism?
Are low processes that happened in the past. Canyons by rivers cutting trough rock were not result of large scale.
What is uniformitarianism?
This theory states that the geologic processes that shape earth are uniform over time.
Is the geologic process that is “a key to the past”
Uniformitarianism
What is variation?
Is the differences in the physical traits of an individual from those of other individuals
What is intraspecific variation?
Is variation among individuals of the same species.
Explain what Interspecific variation is
Are differences in variation among species.
What is adaptation?
Is a feature that allows an organism to adapt to it’s environment.
In what island did Darwin discover the importance of the adaptation in organisms?
In the Galàpagos islands
What did Darwin discover, too?
That the Earth is much older than 6000 years
Explain what artificial selection is
When humans make use of genetic variation in plants and animals. This is, humans determine which traits are favorable and breed the individuals that have those traits.
Heritability is…
The ability to pass traits from one generation to the next.
What is natural selection?
Is a mechanism by which individuals have inherited beneficial adaptations and produce more offspring on average to do other individuals
What is population?
Is a group of individuals that live in the same area.
Explain what overproduction is
Is to have many offspring and some individuals can die
Descent with modification is…
Natural selection will result in species with adaptations that are well suited for survival and reproduction.
