Study Notes
Evolution
- Evolution is a gradual change of organisms over time, resulting in modern organisms descending from ancient organisms.
- Evolution occurs in populations, not individuals, due to changes in the gene pool.
Mechanisms of Evolution
- Mutation: a random change in a population's gene pool, resulting in new alleles and variation in the population.
- Gene flow: the transfer of genes from one population to another, leading to increased similarity between populations.
- Genetic drift: a mechanism of evolution that occurs when a small group of individuals leaves a population and establishes a new one in a geographically isolated region.
- Natural selection: the process by which the fittest individuals survive and contribute their genes to their offspring, driving adaptation to the environment.
Charles Darwin
- Considered the father of modern evolution
- Spent 25 years gathering facts about evolution before publishing his book "The Origin of the Species" in 1859
- Traveled the world as a naturalist on the ship Beagle, observing and analyzing the environment
Geologic Time Scale
- A hierarchy of time period categories used to characterize geologic time
- The broadest category is the Eon, followed by Era, Period, Epoch, and Age
- Fossil records are used to date and compare rocks across geological time
- The International Chronostratigraphic Chart is a standard chart showing the relationships between the various intervals of geologic time
Time Period Categories
- Eon: the broadest category of geologic time
- Era: a subdivision of an eon, characterized by a specific type of life form
- Period: a subdivision of an era, characterized by a specific type of life form
- Epoch: a subdivision of a period, characterized by a specific type of life form
- Age: the smallest unit of geologic time, also referred to as a "stage"
