Mensual November Flashcards
is a group of organisms that can reproduce and have fertile offspring.
Species
the biological change process by which descendants come to differ from their ancestors.
Evolution
classification system from kingdom to species
Linneaus
species shared ancestors rather than a rising separately
Buffon
more-complex forms developed from less-complex forms
E.Darwin
environmental change leads to use or disuse of a structure
Lamarck
There were three theories of geologic change
-catastrophism
– gradualism
– uniformitarianism
is the prevailing theory of geologic change.
Uniformitarianism
is a feature that allow an organism to better survive in its environment.
Adaptation
is the process by which humans select traits through breeding.
Artificial selection
is a mechanism by which individuals that have inherited beneficial adaptations produce more offspring on average than do other individuals.
Natural selection
is the ability of a trait to be passed down.
Heritability
are similar in structure but different in function
Homologous structures
have a similar function
Analogous structures
are remnants of organs or structures that had a function in an early ancestor.
Vestigial structures
