Bio Lecture Exam 3.1

Chapter 10 Content of Exam

QuestionAnswer
Phases of Life's Origin Phase 1 - The formation of small molecules containing carbon and hydrogen Phase 2 - The formation of self-replicating, information-containing molecules Phase 3 - The development of a membrane, enabling metabolism and creating the first cells
The Basic Units of Biodiversity Species
Scientific Name Parts 1. Genus 2. Specific Epithet (Species)
Linnean System (Domanin)-kingdom-phylum-class-order-family-genus-species
3 Kingdoms Animal, plant, mineral
Hybridization The interbreeding of closely related species
Morphological Species Concept Focuses on how species look to relate them
Speciation One species splits into two distinct species
Allopatric Speciation Speciation with geographic isolation
Sympatric Speciation Speciation without geographic isolation
Evolutionary Trees Show common ancestor, reveals evolutionary history and sequence of speciation events
Evolutionary Tree Diagram . . . .
Monophyletic Groups A group in which all of the individuals are more closely related to each other than to any individuals outside the group
Convergent Evolution Occurs when populations of different organisms live in similar environments and so experience similar selective forces
Analogous Traits Characteristics similar because of convergent evolution, not a common ancestor
Homologous Features Features inherited from a common ancestor
Macroevolution Evolution above the species level
Microevolution A slight change in allele frequencies over one or a few generations
Adaptive Radiation Times of extreme diversification
3 Phenomena May Trigger Adaptive Radiation: 1. Mass extinction events (comp. eliminated) 2. Colonization events (new resources, less comp) 3. Evolutionary innovations (evolution of an innovative feature)
All Living Organisms Divided into 3 Groups: Bacteria, Archaea, Eukarya
Groups of Archaea 1. Thermophiles 2. Halophiles 3. High and Low pH tolerant archaea 4. High-pressure tolerant 5. Methanogens
Groups of Eukarya Plants, animals, fungi, and protists
