A heritable trait that increases an organism's ability to survive and reproduce in its environment.
What Is Adaptation?
The observable response or action of an organism to an internal or external stimulus.
What Is a Behavior?
The interaction between organisms or species vying for the same limited resources, such as food, water, or territory.
What Is Competition?
A measure of an organism's ability to survive and pass its genes on to the next generation.
What Is Fitness?
The total collection of all the different genes and alleles present in a specific population at a given time.
What Is a Gene Pool?
The difference in DNA sequences between individuals within a population.
What Is Genetic Variation?
The specific physical area or location where a particular species or population lives and interacts.
What Is Geographic?
The separation of populations or species, preventing them from interbreeding and exchanging genetic material.
What Is Isolation?
The study of the physical form, shape, and structure of organisms and their specific structural features.
What Is Morphology?
The process where organisms better adapted to their environment tend to survive and produce more offspring.
What Is Natural selection?
The observable physical or biochemical characteristics of an organism, determined by both its genetic makeup and environmental influences.
What Is Phenotypic?
The process by which information from a gene is used to synthesize a functional product, typically a protein.
What Is Expression?
The study of how the internal parts and systems of living organisms function to maintain life.
What Is Physiology?
A group of individuals of the same species living in the same geographic area at the same time.
What Is a Population?
Biological barriers that prevent members of different species from interbreeding and producing fertile offspring.
What is Reproductive isolation?
A form of natural selection where individuals with certain inherited traits are more likely than others to obtain mates.
What Is Sexual selection?
The evolutionary process by which new, distinct species are formed.
What Is Speciation?
A group of similar organisms capable of interbreeding to produce fertile offspring.
What Are Species?
A specific characteristic or feature of an organism that is determined by its genes, the environment, or both.
What Is a Trait?
Horizontal stacks of rock or soil that often contain fossils, helping biologists and paleontologists determine the relative age and evolutionary history of organisms.
What are Sedimentary layers?
