What term describes the theory that natural disasters shaped Earth's landforms and caused species to become extinct?
Fossils are traced to organisms that lived in the past.
What was not commonly believed in the 1700s?
What term describes a feature that allows an organism to better survive in its environment?
What term describes features that are similar in structure but different in function?
the process of biological change by which descendants come to differ from their ancestors.
Swedish botanist who developed a classification system for all types of organisms known at the time.
a group of organisms so similar to one another that they can reproduce and have fertile offspring.
French naturalist of the who proposed that species shared ancestors instead of arising separately; also he said that the earth was >6000 years old.
Charles Darwin's grandfather; English doctor and poet; proposed that all living things were descended from a common ancestor.
French naturalist who proposed that all organisms evolved toward perfection and complexity; he did not think that species became extinct.
states that natural disasters such as floods & volcanic eruptions have happened often during Earth's long history and that these events shaped landforms and caused species to become extinct in the process.
one of the leading supporters of the argument for an ancient Earth; wrote "Principles of Geology" and agreed with Hutton on Uniformitarianism.
the difference in the physical traits of an individual from those of other individuals in the group to which it belongs.
a feature that allows an organism to better survive in its environment; they can lead to a genetic change in the population over time.
the process by which humans change a species by breeding it for certain traits.
a mechanism by which individuals that have inherited beneficial adaptations produce more offspring on avg than do other individuals.
English economist who proposed that resources such as food, water, and shelter were natural limits to population growth.
variation, overproduction, adaption, descent with modification
Charles Darwin and Alfred Wallace came up with 4 main principles to the theory of natural selection.
a measure of the ability to survive and produce more offspring relative to other members of the population in a given environment.
features that are similar in structure but appear in different organisms and have different functions.
Because all living things have DNA, they share the same genetic code and make most of the same proteins from the same 20 amino acids.
