Evidence for evolution: anatomy, molecular biology, biogeography, fossils, & direct observation. Since Darwin’s time, the evidence from these sources has become considerably stronger and more comprehensive, while biological disciplines that emerged more recently—genetics, biochemistry, physiology, ecology, animal behaviour (ethology), and especially molecular biology—have supplied powerful additional evidence and detailed confirmation. aspects of humans that underlie them. They then ask why particular features evolved in humans and not other animals and attempt to recon-struct when they appeared in human evolution and under what circum-stances. Examples of Evolving Species. In doing so, they review the entire scope of human evolution and provide a large set of working hypoth-eses for future testing. Attend in person Watch the webinar. Teeth probably originated as dermal structures, which secondarily spread to the mouth, where they became associated with bones. 7b) potentially reflects isotopic exchange in a closed system. The word evolution (from the Latin evolutio, meaning "to unroll like a scroll") was initially used to refer to embryological development; its first use in relation to development of species came in 1762, when Charles Bonnet used it for his concept of "pre-formation," in which females carried a miniature form of all future generations.

Natural Selection and Cultural Inheritance. All living creatures are related by descent from common ancestors. Those that are lacking in such fitness, on the other hand, either do not reach an age when they can reproduce or produce fewer offspring than their counterparts. In the mid-1800s, Charles Darwin famously described variation in the anatomy of finches from the Galapagos Islands. Boston, American Unitarian Association, 1913 Updates?

Evolution and natural selection. Biologists have reached a strong consensus about the validity of universal common descent, the power of natural selection, and the importance of studying fossils, embryology, biogeography, homologous structures, etc. When it comes to the evolution of life, various philosophers and scientists, including an eighteenth-century English doctor named Erasmus Darwin, proposed different aspects of what later would become evolutionary theory.
