BIO 3102 Study Guide - Comparative Embryology, Polyploid, Comparative Anatomy
Document Summary
Analogy: comparison between two species based on their structure ex. comparison between bats and birds wings two different analogies: homologous and homoplasy. One of the reactants in the carbon cycle reacts with ca and other metals in the water to form sediments that fall to the sea bed. Animal adapt to the environment they are living in. Essence of being a certain animal differs depending where the animal lives. Catastrophic theory: theory that the earth has been affected in the past by sudden, short-lived, violent events, possibly worldwide in scope. The cell is the basic unit of life. Cells arise from pre-existing cells. proposed by schwann and schleiden. Comparative anatomy: (ex. bones in the arm of whales, humans, and bats are the same) Comparative embryology (how an embryo changes over time) vestigial structures: (ex. goosebumps, nictatating membrane in the corner of the eye) (appendix is actually not a vestigial structure) biogeography molecules: follow common ancestries using dna and proteins.
