Structure and Function
Cell
Structure The beautiful artwork of David Goodsell is available at this
Website. Click on the "Gallery" to view a small portion of a eukaryotic
cell. The thin yellow layer is the lipid portion of the plasma membrane.

through the internal membranes of a eukaryotic cell.
Phagocytosis
At this site you can view an amoeba eating yeast via a specialized type
of endocytosis known as phagocytosis. The yeast are stained red, and a
special protein inside the amoebae has been stained green. You can see
how the protein reorganizes as the amoeba engulfs the yeast.

Evolution
Introduction
to Evolutionary Biology This very complete, though sometimes advanced,
introduction to evolution includes discussions of: common misconceptions,
genetic variation, natural selection, sexual selection, genetic drift,
mutation, recombination, gene flow, and speciation, extinction, and punctuated
equilibrium.
Paleontology
Without Walls This is a great site for evolutionary biology. It includes
three areas: Phylogeny - The "Family Tree" of Life, Geological Time, and
Evolutionary Thought. By following the Evolutionary Thought link, you can
find information about a number of scientists who have made historical
contributions to evolutionary theory, including Buffon, Cuvier, Lamarck,
Darwin, and Malthus.
Charles
Darwin The complete texts of The Voyage of the Beagle and On the Origin
of Species are given here.
Virtual
Galapagos Explore the geography, geology, and biology of Galapagos
Islands, where Darwin made many of the observations which led him to develop
his theory of evolution by natural selection.
Past
Extinction This section of the Bagheera Endangered Species Classroom
presents a nice discussion of biodiversity and extinction. It distinguishes
among different "types" of extinction, discusses mass extinction, and presents
eleven case studies, including the passenger pigeon, Pleistocene megafauna,
and Neanderthals.
Museum
of Paleontology University of California's Museum of Paleontology has
an enormous collection of on-line exhibits can be explored to learn about
the story of life on earth.
Cosmic
Ancestry The series of steps necessary for the origin of cellular life
from inorganic molecules raises many questions and presents many problems.
Alternative theories have been suggested to explain the origin of life
on Earth. One of these is that life on Earth originated from outer space.
This Web site argues for that possibility.
From
Primordial Soup to the Prebiotic Beach This "Access Excellence" Web
site presents an interview with Dr. Stanley Miller, who first synthesized
amino acids in his famous 1953 experiment. Dr. Miller describes the early
prebiotic experiments that led to his own classic study and why his work
was more successful.
Critters,
Critters, Everywhere The discovery of traces of single-celled organisms
in a meteorite from Mars reminds us that life can inhabit some pretty strange
places. On Earth, life has recently been discovered on the ocean floor,
in mile-deep rock, and in temperatures above the boiling point of water.

Online Textbooks and Resources
The
Woodrow Wilson National Leadership Program in Biology Since 1991, the
National Leadership Program for Teachers has offered programs in a variety
of biology topics: human ecology, bioethics, biotechnology and genetics.
Although the topics are diverse, there is an underlying perspective common
to all of them. Each residential Core Institute approaches its subject
in an integrative way, focussing on the particular theme but using that
theme to illuminate other areas of biology.
BIODIDAC
A collection of images for teaching biology.
Biology
Labs On-Line! Biology Labs On-Line offers a series of interactive,
inquiry-based biology simulations and exercises designed for college and
AP high school biology students.
