Chapter 20 PHYLOGENY Introduction to Phylogeny Phylogeny is the evolutionary history of a species or group of related species Discipline of systematics classifies organisms and determines their evolutionary relationships Taxonomy is the ordered division and naming of organisms Cladistics Cladistics classifies organisms by common descent A clade is a group of species that includes an ancestor and all its descendents Using Derived Characters Characters can be used to infer evolutionary relationships. Molecular Clocks Molecular clocks use mutation data in related genes from different species Number of nucleotide changes is assumed to be proportional to the time since last common ancestry ie. Few changes = little time passed; many changes = lots of time passed

Ch 23: The Evolution of Populations Overview Microevolution is a change in allele frequencies in a population over generations Concept 23.1: Genetic variation makes evolution possible Genetic Variation Genetic variation among individuals is caused by differences in genes or other DNA segments Phenotype is the product of inherited genotype and environmental influences Natural selection can only act on variation with a genetic component Formation of New Alleles New genes and alleles can arise by mutation or gene duplication A mutation is a heritable change in nucleotide sequence of DNA Only mutations in cells that produce gametes can be passed to offspring A point mutation is a change in one base in a gene The effects of point mutations can vary:

0 1 Introduction: Evolution and the Foundations of Biology Overview: Inquiring About Life An organism?s adaptations to its environment are the result of evolution For example, a beach mouse?s light, dappled fur acts as camouflage, allowing the mouse to blend into its surroundings Inland mice of the same species are darker in color, matching their surroundings Evolution is the process of change that has transformed life on Earth Figure 1.1 Figure 1.2 Biology is the scientific study of life Biologists ask questions such as How does a single cell develop into an organism? How does the human mind work? How do different forms of life in a forest interact? Concept 1.1: Studying the diverse forms of life reveals common themes

Ecology: Definitions Ecology: The scientific study of the interactions between organisms and their environment that determines the distribution and abundance of organisms Ecology is a science Environmentalism is a cause Conservation Biology is the integration of these two: using science to support a political cause Population ecology: experimental field approach: natural populations manipulated to test specific predictions arising from controversial ecological theory Organismal ecology: studies how an organism?s structure, physiology, and (for animals) behaviour meet environmental challenges Population: all the individuals of the same species within an ecosystem Population ecology focuses on factors affecting how many individuals of a species live in an area

The Hardy-Weinberg principle The Hardy-Weinberg principle: the frequency of alleles and genotypes in a population?s gene pool will remain constant from one generation to the next. Provided that only Mendelian segregation and recombination of alleles are at work Describes a population that is not evolving The Hardy-Weinberg principle describes a hypothetical population Changes to allelic frequency and genotype always occur in real populations The equation p2 + 2pq + q2 = 1 p2 and q2 represent the frequencies of the homozygous genotypes 2pq represents the frequency of the heterozygous genotype Conditions of the Hardy-Weinberg Principle Population size = extremely large No gene flow can occur (no immigration or emigration of individuals) No mutations No natural selection
