Introduction to Evolution
Evolution - the process by which different kinds of living organisms are thought to have
developed and diversified from earlier forms during the history of the earth

Definition: the study of the diversification of living forms, both past and present,
and the relationships among living things through time; relationships are
visualized as evolutionary trees

1.1 An Introduction
In 1913, Niels Bohr introduced a set of predictions about the atom. Bohr
depicted an atom as a miniature solar system with the concentric electron
paths forming the planetary orbits and the nucleus at the center like the sun.
What is Darwinism?
by Joel Hanes (pg. 12-14)
Darwinism vs. Neo-Darwinism:
Darwinism - origin of species through natural selection
neo-Darwinism (modern synthesis) - Darwinism + genetics
genetic is hard inheritance
From Erust Mayr:
Early Concepts of Evolution: Jean Baptiste Lamarck
Darwin was not the first to come up with the idea of speciation.
In the 18th century, Buffon and other naturalist started to question creationism.
Fossil Evidence of Evolution
Understand the relevant information provided by the rocks and fossils; how does this
evidence support evolution?

Evolution as Fact and Theory
by Stephen Jay Gould (pg. 6-11)
Stephen J. Goulds comments:
common public idea of theory is imperfect fact (incorrect)
facts are the worlds data

The study of identification and nomenclature - leads to biodiversity
alpha taxonomy - identifies new form
Ex: Greenland seal is distinct from a harbor seal

Origins and History of Evolutionary Thought
Endemic: only found in one location
galapagos mocking birds
marsupials - dont have extraembryonic membranes like placentals
Gondwana - southern hemisphere

Using the formula below, r = [ln(Nend) - ln(Nstart)] / (number of years) You have
data from a frog population sampled in 1911 and 1921, with and N(1911) = 30
and N(1921) = 352 what is your estimate of r?
r = ln(352) - ln(30) / 10
r = 5.86 - 3.4 / 10
r = 0
