The process of change over time
The preserved remains or traces of ancient organisms.
any heritable characteristics that increases an organism's ability to survive and reproduce in its environment.
How well an organism can survive and reproduce in its environment.
The process where organisms with variations most suited to their local environment survive and leave more offspring.
The study of where organisms live now and where they and their ancestors lived in the past.
Structures that are shared by related species and that have been inherited from a common ancestor.
Structures inherited from ancestors but have lost much or all of original function.
A common group of genes that consists of all genes including all the different alleles for each gene that are present in a population.
Number of times an allele occurs in a gene pool, compared to the total number of alleles in that pool for the same gene.
Trait controlled by only one gene
Trait controlled by two or more genes
A population or group of populations whose members can interbreed and produce fertile offspring.
The formation of a new species
Hutton and Lyell
Concluded Earth is very old and the processes that changed Earth in the past are the same processes that change Earth now.
Proposed theory that organisms pass on traits they acquire in their lifetime. (Incorrect) i.e. Scars
Reasoned if population grew unchecked, there wouldn't be enough living space and food for everyone.
Descent with modification
An idea Darwin proposed that living species are descended with modification from common ancestors.
5 pieces of Evidence of Evolution
Biogeography, fossils, anatomy and embryology, vestigial structures, and genetics.
Any change in the relative frequency of alleles in the gene pool of population over time.
What is evolution in genetic terms?
Sources of Genetic Variation
Mutations, Genetic Recombination in sexual reproduction, and lateral gene transfer.
The success of passing genes to the next generation
Any genetically controlled trait that increases an individual's ability to pass along its alleles.
Natural Selection on Single-Gene Traits
Changes allele frequencies of phenotypes
To avoid the confusion caused by regional names
Why do biologists use a classification system?
This is a classification system in which each species is assigned a two part scientific name
How many levels of classification are there in Linnaeus's classification system?
Is the panda bear more closely related to the sea star or coral snake?
This is the evolutionary relationship among organisms
This is the strategy of grouping organisms together based on their evolutionary history
