Document Summary
Midterm 1 first 5 weeks of material. The study of the origin, maintenance, and diversity of life on earth over approximately 3. 5 billion years. Allows us to infer relationships between any species that has ever lived, track the diversity of life across time, test hypotheses through observation and manipulation. From fossils, dna, behaviours, and morphologies show these relationships. Melded 2 concepts: diversity of life has descended from previously existing species, the often exquisite fit of species to their environment is primarily a result of natural selection. Different shapes of hummingbird beaks fit into different types of flowers to allow them to. Evolutionary biology now informs the way we think about almost all sub-disciplines in biology get food and nutrition. All living things have descended from a common ancestor. Can view all species as a vast branching tree: tip species, branch point divergence. How different organisms are related to each other. One of the most important conceptual foundations of biology.
