BILD 3 Study Guide - Midterm Guide: Advantageous, Plant, Peptide
Document Summary
Chapter 1: evolution, the themes of biology, and scientific inquiry. Chapter 22: descent with modification: a darwinian view of life. Each life had its rung on the ladder: agreed with old testament, saying species were created by god and perfect, linnaeus: developed binomial format for naming species. Adopted nested classification system, grouping similar species into increasingly general categories: attributed resemblance of species to creation pattern, not evolutionary kinship. Ideas about change over time: darwin drew from fossil studies: remains or traces of organisms from the past, fossils found in sedimentary rocks from sand and mud. New layers compress into superimposed layers called strata. Inheritance of acquired characteristics: organism can pass modifications to offspring: thought evolution happened since organisms have innate drive to be more complex, believed organisms were well-suited for life in their environments because of gradual evolutionary change. Bird shot and put into tub to let float. After a month, cut open bird and plant seeds.
