Overview: endless forms most beautiful: a new era pf biology began in 1859 when charles darwin published the origin of species. The origin of species focused biologists" attention on the great diversity of organisms. Darwin noted that current species are descendants of ancestry species. Evolution: can be defined by darwin"s phrase descent with modification each generation is the same but a little different from the generation before it. Evolution can be viewed as both a pattern and a process ex: pattern horses lost toes and got one hoof. Ideas about change over time: the study of fossils helped to lay the groundwork for darwin"s ideas. Fossils are remains or traces of organisms from the past, usually found in sedimentary rock, which appears in layers or strata.
