The differences between the individuals in a species. Example: eye color, skin color, hair color
Variation
The comparison of embryo development of different species.
Comparative Embryology
When no individuals of a species are alive
Extinction
List the 3 evidences of evolution
DNA, Comparing Embryology and Comparing Homologous Structures
A physical or behavioral trait that helps an organism survive and reproduce in its environment
Adaptation
The gradual change of an entire species over time
Evolution
The best adapted to their environment is called:
The fittest
The traces or remains of a once living organism
Fossils
An organ or body part that appears in different animals and is similar in structure and location, but doesn't necessarily share the same purpose.
Homologous Structure
Organisms that are able to survive are more likely to pass their traits onto offspring, which is called
survival of the fittest
A change in the DNA sequence of a gene
Mutation
A molecule that contains the genetic instructions an organism needs to develop, live, and reproduce.
DNA
Process where organisms with favorable traits are more likely to survive and reproduce
Natural Selection
