An early, pre-birth stage of an organism's development.

Fitness is a result of ___________.
What is Adaptation
300
The body parts of organisms that do not have common evolutionary origin but are similar in function
What are analogous structures
300
Favors average individuals. This type of selection reduces variation in a population

300
All the alleles in a populations genes
What is gene pool
300
Morphological adaptations that allow them to blend in with their environments.
What is camoflauge
400
A pattern of evolution in which distantly related organisms evolve similar traits
What is convergent evolution
400
Structures that are reduced forms of functional structures in other organisms.
What are vestigial structures.
400
Favors both extreme variations of a trait, resulting eventually in no intermediate forms of the trait and leading to the evolution of two new species
What is disruptive selection
400
The idea that species originate through a gradual change of adaptations
What is gradualism

All animals are in an embryonic state, before birth.
What is a true answer.

When an ancestral species evolves into an array of species to fit a number of diverse habitats
What is adaptive radiation

500
The evolution of a new species
What is speciation
