A species that no longer exists
What is Extinction
Young that are capable of reproducing and having their own offspring
What is Fertile Offspring
Any movement of genes from one population to another.
What is Gene Flow
section, group, or type of people or animals living in an area
What is Population
The evolutionary history and relationships among different groups of organisms
What is Phylogeny
remains of a once living organism or its behavior
What is Fossils
Different or distinct form or version of something.
What is Variation
A random change in the frequency of a gene in a population over time
What is Genetic Drift
Genetic makeup of populations, including how allele frequencies change over time due to evolutionary forces like natural selection, genetic drift, mutation, and migration
What is Population Genetics
the science of classifying and naming living organisms into groups based on shared characteristics.
What is Taxonomy
A collection of fossils documenting the history of life on Earth
What is Fossil Records
When humans, rather than nature, choose which organisms with specific traits are allowed to reproduce, leading to changes in the characteristics of a species over time
What is Artificial Selection
occurs when a small group of individuals, or founders, breaks off from a larger population and establishes a new, isolated community.
Founder Effect
collection of genes within an interbreeding population at a particular time
What is Gene Pool
Studies or is an expert in the branch of science concerned with fossil animals and plants.
What is Paleontologist
Process of determining the actual age of an object
What is Absolute Dating
Scientific literature by Charles Darwin
What is Origin of Species
Reduction in a population's size, often due to a catastrophic event, leading to a loss of genetic diversity
What is Bottleneck Effect
proportion or percentage of a specific allele present in a population's gene pool
What is Allele Frequency
the change in the genetic makeup of a population over time, driven by processes like mutation,
What is Microevolution
Measures the number of changes, or mutations, which accumulate in the gene sequences of different species over time
What is Molecule Clock
Group of islands that Darwin went to
What is Galapagos
Process where organisms with traits better suited to their environment tend to survive and reproduce more successfully
What is Natural Selection
Allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences.
What is Hardy Theorem
large-scale evolutionary changes that occur above the species level
What is Macroevolution
