Charles Darwin
What theory is Charles Darwin responsible for?
Survival of the fittest/ Natural selection
what type of evidence is shown by comparing proteins and DNA from different species
Those are more similar are more related
Molecular Evidence
Individuals have a choice in who they mate with
Non-random Mating
when two or more species reproduce at different times of the year.
Temporal Isolation
two or more species become more dissimilar
Divergent Evolution
The Galapagos
Organs so reduced in size that they are just traces of homologous structures in other species. Organ has no benefit and causes no harm.
Vestigial Structure
Better adapted (more fit) individuals to their environment survive and reproduce passing on the beneficial genes to offspring
Natural Selection
2 populations are capable of interbreeding, but have different courtship rituals
Behavioral Isolation
Unrelated species become more and more similar
Similar adaptations due to similar environment
Convergent Evolution
What species is Darwin Most famous for studying?
Finches
parts with similar basic structure (derived from same structures in embryo—same common descent), but may vary in function
Homologous structures
The random change in the DNA of an organism
Mutations
wo populations are separated by barriers such as rivers or mountains
Geographic Isolation
One end of the distribution curve has higher fitness.
Selection against one of the extremes.
Directional Selection
what is the name of the ship that Charles Darwin rode around the world?
HMS Beagle
structures that DO NOT have a common evolutionary origin (may look somewhat alike), but have different structures and DO NOT have a common descent
Analogous Structures
The introduction of genetic material by interbreeding from one population of a species to another
Gene Flow
Geographic Isolation is also called...
Allopatric speciation
The individuals in the center of the curve has higher fitness.
Selection against the extreme phenotypes at both ends of the curve
Stabilizing Selection
what is the name of the book that Charles Darwin wrote?
On the Origin of Species
the study of the formation and development of an embryo and fetus
Patterns of embryological development/ Embryology
The change in allele frequencies as a result of chance
Ex : Earthquake, fire, flood etc.
Genetic Drift
Isolation that is not geographic is also called...
Sympatric Isolation
Both of the extreme phenotypes have higher fitness.The average phenotype is selected against.
Disruptive Selection
