Discussion 1: Evolution Briefly describe Darwin's theory of natural selection and discuss how this theory differs from
amarck's ideas about evolution. Why does Darwin's theory work while Lamarck's does not?
What do you think is the difference between science and religion in describing humans' place
in the worldDoes it make a difference for humans if we evolved versus if we were created? In
what ways?

Population Variability

Deriving Genotypic and Allelic Frequencies

Hardy-Weinberg Equilibrium

Evolutionary Genetics

Darwin's Theory of Natural Selection

Darwin's Theory of Evolution by Natural Selection

More individuals are produced each generation that can survive.

Phenotypic variation exists among individuals and the variation is heritable.

Those individuals with heritable traits better suited to the environment will survive.

When reproductive isolation occurs new species will form.

These are the basic tenets of evolution by natural selection as defined by Darwin. The following is a quote from Darwin.

"Variation is a feature of natural populations and every population produces more progeny than its environment can manage. The consequences of this overproduction is that those individuals with the best genetic fitness for the environment will produce offspring that can more successfully compete in that environment. Thus the subsequent generation will have a higher representation of these offspring and the population will have evolved.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
