Chapter 15
The genetic change in species over time, also known as descent with modification?
Evolution
The change in gene frequencies between populations of species over time is known as what?
Microevolution
Systematics is the study of what?
Biodiversity
What is Paleontology?
Study of fossils
2 types of selection:
Natural and Artificial
What is the process in which species start t inherit traits that are more helpful in survival and reproduction?
Natural Selection
What is population genetics?
Study of diversity of populations at gene level
What are the 3 kingdoms of domains?
Bacteria, Archaea, and Eukarya
Phylogeny is what?
"Evolutionary" family tree
Adaptive changes in males and females that lead to an increased ability to secure a mate is known as what?
Sexual Selection
What are the two main principles of Lamark's hypothesis of evolution?
1. Use and disuse
2. Inheritance of acquired characteristics
Why might genetic drift occur?
Due to chance events
Taxonomy
Intentional breeding of certain traits
Artificial Selection
What is gene flow?
Movement of alleles between populations
What counts as biochemical molecules?
DNA, RNA, ATP
What happens in Founder effect?
Isolated individuals form a new population
Uses shared, derived traits to develop a hypothesis of evolutionary history:
Cladistics
What causes bottleneck effect?
Natural disasters
Types of natural selection:
Stabilizing selection, directional selection, and disruptive selection.
List 3 types of evidence of Evolution:
Fossils
Homology
Vestigial Structures
Biochemical evidence
Biogeography
what are the 2 equations is the Hardy-Weinberg?
1. p2+2pq+q2=1
2. p+q=1
What are homologies?
Phenotypes and genotypes with similarities due to shared ancestry.
What are the 2 types of hypothesis in female choice?
Good genes hypothesis and runaway hypothesis
Convergent evolution is...
similarities due to selective pressure.
