Theory Doe
The slight differences within a species, it means that everyone is different!
What is variation?
This favorable trait can help prey to hide from their predators.
What is camouflage?
In natural selection, this is the agent that "selects" for or against traits of an organism.
What is the environment?
Any trace or remains of a once-living organism that has been preserved by natural processes.
What is a fossil?
This species was artificially selected from wolves.
What are dogs?
Organisms often have more ____________ than will survive.
What is offspring?
This is the information passed from parent to offspring.
What is inherited traits or DNA?
The source of all variation.
What are DNA mutations?
This word means the amount of one species in a given area.
What is population?
This chooses the way that a species breeds in artificial selection.
What are humans?
These must be obtained for an organism to survive and there is not enough for all living things.
What is limited resources?
A group of genetically similar organisms that can mate and produce fertile offspring.
What is a species?
When a characteristics benefits a living thing and allows them to reproduce we call them this.
What is an advantageous trait?
This part of Ecology makes their energy using the sun.
What are producers?
These spots in the Earth's crust caused the formation of islands in the middle of the Pacific Ocean.
What are volcanos or tectonic hotspots?
These are the finite things in an environment that all living things need.
What is Resources (Shelter, Food, and Water)?
These graphics show the relationships between species and usually are organized by traits or genes.
What is a cladogram?
The maximum amount of living things an environment can support.
This part of the ecosystem needs to eat biomass to gain energy.
What are consumers?
This is one way a species can become isolated from another species due to space, land or sea.
What is geographic isolation?
The process whereby organisms that have advantages survive and pass their genes onto their offspring.
What is Natural Selection?
This is when traits are selected for animals and plants by humans through selective breeding.
Artificial Selection
When a living thing has a "strong" chance of passing off their traits to their offspring.
What is fitness?
This is a structure that is no longer functional, but shows evidence of evolution.
What is a vestigial structure?
This type of growth is seen when there is an infinite amount of resources to support a populations growth.
What is exponential growth?
