Evolution
Natural selection
Evolution in action
Peppered moths
Pesticide resistance- ex) red allele is resistant
Antibiotic resistance- staph infection
Stop the super bug
Use of antibiotics drive bacterial populations to evolve resistance
Antibiotic resistance is inevitable
Control resistance by changing practices
Before Darwin
Lamarck- traits acquired during lifetime of an individual were passed on to offspring
Acclimation
Transient change in an individual, no change in alleles
Ex) higher elevation change
Adaptation
Change in alleles in a population
Natural selection leads to adaptation
Charles Darwin
Theory of natural selection
Published on origin of species
Descent with modification
Influences of Darwin- Erasmus Darwin
Grandfather of Darwin
Physician
Modern life evolved from simpler organisms
Proponent of Lamarckian Evolution
Influences of Darwin- Charles Lyell
Principles of geology
Earth is older than 6,000 years
Earths geology is formed by slow moving forces
Influences of Darwin- Thomas Malthus
Essay on principles of population
Human population are limited by factors like food and water =disease
Some individuals die, some survive
Influences of Darwin- Voyage of the Beagle
(1831-1836)
Had bad days
Galapagos
Influences of Darwin- Alfred Russell Wallace
Closely related species occupied neighboring geographic areas
Barriers separated related species
Theory of natural selection
Darwin publishes in 1859 before Wallace
Natural Selection
Survival of the fittest
Genetic contribution that an individual makes to the next generation
Survive, reproduce, and offspring quality
Misconceptions of Evolution
Not the biggest/ strongest Organisms not adapted to future conditions, but the current Organisms not perfect Evolution not forward thinking Evolution is not random
Darwin’s Critics
Evolution is not demonstrated
No fossil intermediates
Too complex for a random process
Natural selection does not imply evolution
Irreducible complexity - watchmaker argument- too complex to invent randomly
