Why is evolution important? - (answer)- diversity of life
- artificial selection
- pathogens/ health (natural selection)
why is losing a branch vs losing a tree more important? - (answer)- losing a tree is
more important since there is a larger population size, and it is one of the more
recent ancestors to all of the past ancestors which need to be protected
- if these animals were lost, pieces of history would be lost too
- if you only lost a branch there is less population, and they have already created
common ancestors with a part of their DNA in them
Redi's experiment 1668 - (answer)- showed that spontaneous generation (of life)
was not how things worked
- early example of empirical hypothesis testing using controls
- experiment where meat was left in jars, some open, some un-opened, the meat
that was unopened flies and maggots could not get in
Jean-Baptiste Lamarck - (answer)This man developed the first cohesive theory of
evolution after his studies of biology
- thought that shorebirds would want to stretch their legs to stay out of the mud
- thought that these traits would be a result of evolution
- doesn't work like this

what are the five major developments that preceded darwins "on the origin of
species" - (answer)1. explanations moved from supernatural to methodological
naturalism
2. from catastrophism to uniformitarianism
3. from logic and pure reason to observation, testing, and refutation
4. from unchanging world to a world in flux
5. away from the idea of spontaneous generation to the idea that species come
from other closely related species
Darwin's two fundamental insights - (answer)1. natural selection: nature selects
the most successful variants
2. ancestry: all species descended from one or a few common ancestors: new
species arise from pre-existing species
two concepts noted by both charles darwin and alfred wallace - (answer)1. living
species tend to be most similar to other species that geographically nearby
2. species in the fossil record tend to be most similar to other species that lived
around the same time
evolutionary biology - (answer)the study of the origin, maintenance and diversity
of life on earth over approximately the past 3.5 billion years
artificial selection - (answer)human-directed selective breeding
