- comparative embryology
- study of development of organisms
- comparative anatomy
- looking at anotomy of organisms (homologous or analogous, divergent or convergent)
- analogous structures
- structures in different organisms with different evolutionary origins but the same function- results from convergent evolution (whale and shark fins)
- Levels of orginazation
- Molecules, cells, groups of cells, organism, population, community, ecosystem, biosphere
- homologous structures
- structures in different organisms that have same evolutionary origin but different functions- results from divergent evolution (bat wing, human hand)
- examples of natural selection
- fitness, producing viable offspring
- Other types of Cues
- tactile, visual, auditory, chemical (pheremones)
- Visual Cues
- Example- baboon opens mouth wide, showing dominance (active)
- Science
- Knowledge obtained through use of scientific method
- environmental pressure
- change in environment (climate, number of predators)
- variation
- meiosis and fertilization, mutation ( changes in DNA)
- Darwin
- February 12, 1809
- evidence of evolution
- comparative anatomy, fossil evidence, comparative biochemistry, comparative embryology
- Natural selection
- Selection by nature of the fittest organisms
- Spontaneous generation
- Hypothesis (disproven) stating that life could arise from nonliving matter
- comparative biochemistry
- looking at dna, rna, and proteins
