Chapter 15
Diagram that reflects evolutionary relationships.
Evolutionary tree
Genetic change in a species over time
Evolution
What are three mechanisms that cause evolution in populations?
Natural selection, genetic drift, gene flow
Movement of alleles between populations
Gene flow
The study of biodiversity
Systematics
The father of evolution
CHarles Darwin
Remains or traces of organisms in the past
Fossils
A change in gene frequencies in a population over time.
What is Micro evolution
Group of the same species living in the same area that share the same gene pool.
What is a population?
Evolutionary "family tree"
Phylogeny
Rock layers formed by new layers of sediment compressing older ones
Strata
The belief that periods of catastrophic extinctions occurred.
Catastrophism
The collection of the alleles of all genes in all individuals within a population.
What is a gene pool?
What is the Hardy-weinburg expression?
p^2+2pq+q^2=1
branch of biology that identifies, names, and organizes biodiversity into different categories
Taxonomy
The 2 principles of Lamarck's hypothesis of evolution
Use and disuse, Inheritance of acquired characteristics
The intentional breeding of certain combination of traits to produce a desirable outcome
Artificial selection
The percentage of each allele in a populations gene pool.
Allele frequency.
Changes of allele frequencies in a gene pool due to chance
Genetic drift
Name the three domains
Bacteria, Archaea, Eukarya
the resemblance of two groups in the present classified separately
Transitional fossils
Similarity in characteristics from a shared ancestry
Homology
Name all the conditions of the Hardy Weinberg Equillibrium
No mutations, no migration, large gene pool, random mating, no selection.
Occurs when plants or animals migrate between populations
Gene flow
Name the eight levels of classification
Domain, kingdom, phylum, class, order, family, genus, species
