Evidence
Body parts that no longer serve a function are called?
Vestigial organs
Who proposed the theory of natural selection
Charles Darwin
Darwin noticed that more offspring are produced than can survive. This is called
Overproduction
Organisms with traits that increase survival and reproduction are most likely to pass those traits on. This is called
Natural selection
Random changes in allele frequency within a population are called
Genetic drift
Fossils dating uses radioactive isotopes to determine fossil age. True or False
True
Which economist influenced Darwin with his ideas on exponential population growth
Thomas Malthus
Differences among individuals in a population are called
Variation
What are the three main types of adaptations
Behavioral, Structural, & Physiological
Movement of individuals between populations introducing new alleles is called?
Gene flow (migration)
Body parts that share a common ancestry but may have different functions are called
Homologous structures
Which geologist's work on slow geological change influenced Darwin
Charles Lyell
A trait that helps organism survive in its environment is called
Adaptation
When a new species forms from a pre-existing species, it is called
Speciation
Mating that is not random affects allele frequencies. True or false
True
DNA and protein comparisons are examples of what type of evidence
Molecular evidence
Darwin collected most of his data on which ship
H.M.S Beagle
Competition between individuals of the same species for resources is called
Intraspecific competition
Competition between individuals of different species for resources is called
Interspecific competition
A small group starts a new population with limited alleles, leading to genetic differences. This is called
Founder effect
the study of pre-birth development stages to show evolutionary relationships is called
embryology
What are the two parts to Jean-Baptiste Lamarck theory
Use and disuse & Inheritance of acquired characteristics
Give an example of a structural adaptation that Darwin might have observed in finches
Different beak shapes suited for available food
“Survival of the fittest” is often misunderstood. What does the term actually mean in evolutionary terms?
Environment dictates what variations are favourable. Survive and reproduce.
A sharp reduction in population size due to a disaster that changes allele frequencies is called
Bottleneck effect
