Introduction to Evolution
Use your textbook &/or appropriate resources to answer the following questions.
1. Why was Darwins theory of evolution revolutionary at the time he proposed it?
In Darwin's time, most people were religious and because of this,
1. What do we mean when we say that natural selection acts on phenotypes?
The phenotype includes not only an organism's physical traits but also things like its metabolism and
behavior, and the genotype may include information that doesnt affe
HActivity: Is Different Better?
Introduction: In this investigation, you will examine data dealing with humans, the seeds of a plant,
and tail lengths of deer mice. You will compare variation within each of the areas, measure the
variations, and graph the
GENE POOL ANALYSIS
A: Sickle Cell Anemia
Sickle-cell anemia is controlled by an autosomal recessive gene. Individuals with this gene in a
homozygous state produce abnormal hemoglobin which differs from normal hemoglobin in 1 amino acid.

Lab Population Genetics and the Effect of Various Factors on Gene Frequency
Introduction: The Hardy-Weinberg Principle will allow gene frequencies in a population at equilibrium to
be determined. Equilibrium will be maintained if the following condition
Population Genetics and Evolution
In this investigation you will do calculations using the Hardy-Weinberg equation to study gene frequencies
and the effects of various factors on the gene frequencies in a population. You will find a calculator very
EDating of Fossils
It is possible to date portions of the earths crust, and the organisms that lived on it by making use of
radioactive materials and their decay products. Radioactive elements are those which emit high-energy
radiation, in the form of alp

For centuries, scientists have used a variety of methods to classify organisms within taxonomic systems.
In contrast, Darwinian classification systems group organisms b
The Need for a Circulatory System
1. Larger and more complex multicellular organisms have body cells that do not come into
contact with the fluids of the external environment (air or water). Individual body cells in
a multicellular animal are in a fixed p

Part I: Evolution of the Horse
The horse has evolved from hyracotherium, a small creature standing less than 0.4m tall, to the modernday horse, a much taller animal standing approximately 1.6 m tall
What is Blood Pressure?
Is the force exerted by the blood against the walls of the arteries
Due to pumping action of the heart and resistance of the elastic
