Darwins Finches
Finches living on separate islands adapted differently from each other because of
What is "Geographic Isolation"
Bacteria reproduce in a way in which the off spring is an exact copy of the parent.
What is "asexual reproduction"
The type of evolution that is driven by environment and competition for resources.
What is "Natural Selection"
What is "artificial selection"
New traits, due to a genetic mistake, that add to a gene pool
What is "Mutation"
The finches are an example of this type of Genetic Drift
What is "Founder Effect"
Medicine that humans develop to kill bacteria
What is "antibiotics"
Selective breeding done by human intervention
What is "artificial selection"
Genetically Modified Organism
The shrinking of a population as non-favorable traits become less common.
What is "genetic drift"
The relationship of the original finches on the mainland to those on the Galapagos Islands
Common Ancestor
This results in genetic variety in bacteria.
what is "mutations"
A change in a species over time
What is "evolution"
A negative result of artificial selection is inbreeding, leading to less _____________ _______________.
What is "genetic variation"
Migration or when a population moves to a new area
What is "gene flow"
By adapting to the food sources available the finch found their place in their ecosystem.
What is "niche"
Antibiotic-resistant bacteria will survive to reproduce and pass on the favorable trait to their offspring.
What is "natural selection"
Adaptations WITHIN a species that pass to off spring, changing the species, but not creating a new species.
What is "Microevolution"
Choosing a mate and artificial selection are types of __________________.
What is "non-random mating"
A population suddenly gets smaller due to a random event.
What is "bottleneck"
A single species gives rise to other species, spreading out like a circle.
What is "adaptive radiation"
Nonresistant bacteria die off, and their traits are no longer available to the species, shrinking the ______ ______.
what is "gene pool"
Adaptions that, over time, result in new species with a common ancestor.
What is "macroevolution"
Changing an organisms genetics in a lab
What is "genetic engineering"
A population changes so much that it becomes two different populations that evolve into two different species.
What is "speciation"
