Natural Selection
A process by which heritable characteristics of a population change such that organisms become better able to survive.
What is adaptation?
All of the organisms of one species within a particular ecosystem.
What is population?
A change in the DNA sequence of a chromosome.
What is mutation?
Descent with modifications from preexisting species.
What is evolution?
Come in, grab your journal, and find a chair to sit in.
What is the expectation of entering Ms.Viven's classroom?
The sum of the different forms of living things in a given area or population.
What is biodiversity?
Differential survival and reproductive success among a group of organisms due to differences in the inherited traits or characteristics of the organisms.
What is natural selection?
The movement of organisms into an area.
What is immigration?
Similarities between characteristics due to their origination from a common ancestor.
What is homologies?
The most common question Ms.Vivens' students ask when doing a drawing assignment.
What is "do we have to add color?"
An organism's ability to survive and produce viable, fertile offspring.
What is biological fitness?
A biotic or abiotic environmental factor that restricts the growth of a population.
What is limiting factor?
To leave one's country or region for another.
What is emigration?
The divergence of populations or subpopulations of the same species to the point where they can no longer interbreed and generate fertile offspring.
What is speciation?
Ms.Vivens' phrase about going to the restroom.
What is "Yes, when the pass comes back?"
The scientist who developed the theory of evolution by natural selection to explain the observed differences among living things.
Who is Charles Darwin?
The ability to produce fertile offspring.
What is reproductive success?
The exchange of genetic material between homologous chromosomes during meiosis; contributes to genetic variation.
What is crossing over?
A long period of time in which little or no change occurs within a species.
What is stasis?
The variety of gene combinations that exist within a population.
What is genetic variation?
Groups of organisms of the same species that have diverged to have different characteristics but can still interbreed to produce fertile offspring.
What is subspecies?
A reduction in the size of a population to a single or a few individuals, resulting in loss of genetic variation.
What is bottleneck effect?
Similarities in structures among species that exist because of descent from a common ancestor.
What is anatomical homologies?
