BIO 185 Lecture 1: Lecture 1
Document Summary
1/30/15 emergent properties: property or function that emerges upon increasing the complexity ex. making atp from components into a system, electron transport chain. Unity: dna in all organisms, backbones in sh and humans, homologous structures. Homologous structures: examples about mammals and the structures of the hands or. Ns or wings (the bones) - use comparative anatomy and embryology. Unity of life: shared basic cellular structure, shared biochemistry (proteins, dna, rna, biochemical pathways. How can we tell the origin of the disease: question 2: if sca is detrimental to humans, why has the mutant gene (bad allele) been maintained through so many generations check slides for other unit questions. Diversity: if each species eventually diverges into another species, that is how we will make millions and millions of species. Unity: common ancestor must have had some desirable traits, which will stay in the species" if it suits the environment.
