Evidence for Evolution
The type of evidence found in sedimentary rock and provides a record over time
What are fossils?
Introduces new alleles into a population's gene pool due to changes at the molecular level. Sometimes neutral, beneficial or harmful in nature
Mutations
this principle is used to determine changes in
What are allele frequencies?
Evolution on a small scale. We can see with direct observation
What is microevolution?
Darwin's mechanism for evolution
What is natural selection
Evidence at the molecular level found in one's nucleus
What is DNA sequencing, DNA or microbiology
Different survival and reproductive success rates among individuals with different genotypes lead to changes in allele frequencies.
What is natural selection?
What is p + q = 1
This type of evolution you see in more complex organisms. Takes 1000 of years to see changes
What is macroevolution
Darwin travelled here and studied the finches
What is the Galapagos islands
The type of evidence that is indicated at very early stages of fetal development
What is Embryology
It can introduce new alleles into the population through migration, death or even birth
What is gene flow?
P2 in the equation refers to
What is homozygous dominant genotype
Symbiotic Relationship in which to organisms evolve together
What is co-evolution
The name of the ship Darwin travelled on
What is the HMS Beagle?
Type of evidence such as Homologous Structures like the forearm of a cat and human
What is Comparative Anatomy
When an original population loses some of its species to create a brand new population therefore decreasing its genetic diversity
What is the founder effect?
If p =0.5 and q=0.5 then the heterozygous genotype frequency in the population using a % is
What is 50%
No common ancestor but this pattern causes similar strucutres to occur in organisms that may live in the same environment
What is convergent evolution?
Darwin's book title
Origin of the species: Descent with modification
Type of evidence that explains distribution of Darwin's finches across the Galápagos Islands
What is biogeography?
Random chance usually caused from a catastrophic event like a fire that wipes out part of the population.
What is bottleneck effect?
Name two things that must be in place for maintain Hardy Weinberg equilibrium in a population
What is no mutation, no gene flow, no genetic drift, random mating, population must be large and equal chance of survival
This pattern occurs from common ancestry and then creates different species. Homologous structures are an example
What is divergent evolution?
Name two people who inspired Darwin's thinking
Who is Malthus, Lamark, Hutton. Lyell, His Grandfather, Wallace, any of these two answers the question
