General Evolution
English naturalist whose scientific theory of evolution by natural selection became the foundation of modern evolutionary studies.
Who is Charles Darwin?
When certain traits increase reproductive success.
What is sexual selection?
Unused organs or structures.
What are vestigial structures?
The process of two or more species evolving in response to changes in each other.
What is coevolution?
The ability to walk upright on two legs.
What is bipedality?
The idea that species change gradually.
What is gradualism?
The movement of alleles from one population to another.
What is gene flow?
The study of where organisms live and where their ancestors live.
What is biogeography?
This happens when unrelated species adapt in similar ways because of environmental conditions.
_____ are categorized by having flexible hands/feet, forward looking eyes, and enlarged brains. Includes, lemurs, monkeys, apes, and humans.
What are primates?
The idea that natural disasters shaped landforms causing species to go extinct.
What is Catastrophism?
The rise of two or more species from one existing species due to reproductive isolation.
What is speciation?
Features that are similar in structure but have different functions.
This happens when closely related species evolve in different ways and become increasingly different.
What is divergent evolution?
A two-word naming system using latin roots to name different species on Earth.
What is binomial nomenclature?
The difference in the physical traits of an individual from those of other individuals in the group to which it belongs.
What is variation?
The process by which individuals inherit beneficial adaptations and produce more offspring than other individuals. (survival of the fittest)
Structures that perform the same function but have different structures.
What are analogous structures?
This proposes that species show little evolutionary change for millions of years but then goes through rapid evolution due to some type of environmental change.
What is punctuated equilibrium?
The saying to remember the 7 (8) levels of organization from most broad to most specific.
What is Dear King Phillip Came Over For Good Soup?
Refers to a heritable trait, whether behavioral, morphological, or physiological, that has evolved through natural selection and enhances an organism's survival and reproductive success in a specific environment.
What is adaptation?
Changes in allele frequency due to chance.
The study that compares and contrasts the embryos of different species to understand their developmental similarities and differences, ultimately revealing evolutionary relationships and common ancestry
What is Comparative embryology?
This is a type of speciation that proposes rapid evolution of many diverse species from a common ancestor.
What is adaptive radiation?
The diagram used to link groups of organisms by showing how evolutionary lines branch from common ancestors.
What is a cladogram?
