First week of Lecture Notes 1/20 Study biology of organisms through… -The diversity of life (patterns) -How plants and animals work (mechanisms) Rest of the lecture was over the syllabus 1/22 Adaptation- trait evolves by selection for a particular function from an ancestor that didn’t have the trait -morphological, behavioral, or molecular -solve problems faced by populations and different populations have different solutions to the same problem Phylogeny- the evolutionary relationships of a group of organism Phylogeny tree- diagram of the ancestral relationships -describe patterns -Tell when large events may have occurred Taxonomy- ordered division and naming of organisms -First developed by Carl Linnaeus - Consists of 2-part names and a hierarchical classification Scientific names are binomial -The first part of the name is the genus -The second part of the name is the specific epithet Both parts name the species, not just the specific epithet From order of most inclusive to least inclusive Domain  Kingdom Phylum Class  Order Family  Genus  Species Taxon- taxonic unit at any level of the hierarchy There are several components needed to build a phylogeny tree -morphological traits -behavior -chemical composition -chromosome number -DNA *These types of data are called characters Character state: variation among characters Branch Point- divergence of 2 species Sister taxa- groups that share a common ancestor Polytomy- more than 2 groups emerge Rooted- last common ancestor of all taxa Monophyletic- consists of an ancestral species and all of its descendants Paraphyletic- an ancestral species and some of its descendants Polyphyletic- includes distantly related species but does not include their most recent common ancestor The three Domains -Bacteria -Archaea -Eukarya The tree of life suggest that animals and fungi are more closely related The phylogeny tree is based largely on rNA genes, because these have evolved slowly Ecology is the study of distribution and interaction of organisms with other organisms and the environment Level of ecology Organism Population Community Ecosystem Landscape Global Organismal ecology- study of how the organism’s structure, behavior, and physiology enable it to survive in its environment Population ecology- studies how and why population size changes through time and what affects population size Community ecology- studies how species interactions affect community structure and organization. \ Ecosystem ecology- studies energy flow and chemical cycling between organisms and the environment Landscape ecology- studies the factors that control exchanges of energy, materials, and organisms Global ecology- studies how the regional exchange of energy and materials influences the function and distribution of organisms across the biosphere.
