Natural Selection
When all species have died out, the species is
extinct, evolved, separated, or adapted?
Extinct
Things that determine whether traits in a population are favorable or unfavorable.
Environmental factors
A characteristic that can be passed from parent to offspring through genes.
Trait
What type of scientist began to realize that Earth was much older than anyone previously thought?
Geologists
A group of organisms that can mate with one another to produce fertile offspring.
Species
Separation, adaption, and reproductive isolation are three parts of mating, isolation, extinction, or speciation?
Speciation
The splitting apart a portion of a population
Separation
Process in which humans select which plants or animals to reproduce based on certain desired traits
Selective breeding
What type of scientist did Darwin serve as while aboard the HMS Beagle?
A Naturalist
Adaptation helps an organism do these 2 things
survive and reproduce in its environment
Both genetic variation and environmental factors affect
selective breeding, habitat loss, living conditions or natural selection?
Natural Selection
The evolving of traits in response to environmental conditions
Adaptation
Process by which organisms that are better adapted survive and reproduce more successfully than organisms that are less well-adapted
Natural selection
What did Darwin notice about the finches of Ecuador and the Galapagos Islands?
The shape of their beaks was adapted to the way the birds got their food.
The process in which inherited characteristics within a population changes over generations such that new species sometimes arise.
Evolution
The evolving of traits in response to environmental conditions.
Speciation
A measure of how much individuals in a population differ genetically
Genetic Variation
Part of natural selection in which sonme individuals die from starvation,m competition, disease, or predation
Struggle to Survive
Who wrote An Essay on the Principle of Population?
Thomas Malthus
The history of life in the geologic past as indicated by traces or remains of living things
Fossil Record
What are 3 different environmental conditions that can lead to the extinction of species?
Increased competition, new predators, and loss of habitat
If a population has high genetic variation, it will have a large variety of what?
Traits
Part of Natural selection in which individuals that are best-adapted to their environment have many offspring
Successful Reproduction
What is the name of the scientist who wrote Principles of Geology?
Charles Lyell
What are the two causes of evolution and diversity of organisms?
Genetic Variation and Environmental Factors
