Introduction Flashcards
Branch of biology that explores the process and patterns of biological evolution
Evolutionary biology
The foundation of evolutionary biology theory
Charles Darwin’s theory of natural selection
Where did darwin present his theory
“on the Origin of species” published in 1859
change in heritable characteristics of populations over successive generations
Evolution
organisms better adapted to their environment tend to survive and reproduce more successfully
Natural selection
Differences in the genetic makeup of individuals in a population. This is where natural selection acts
Genetic variation
Increases an organism’s fitness in a particular environment. Beneficial genetic variation
Adaptation
When new species arise from existing ones. Occurs when population become reproductively isolated
Speciation
Help trace the history of life
Fossil Record
changes of the molecular makeup of organisms over time
Molecular evolution
The study of evolution relationships among species. Evolutionary history
Phylogenetics
Study of how ecological interactions, such as competition and symbiosis, influence the evolutionary process
Ecological and evolutionary interactions
