What is the bottom layer/deeper layers?
Similar structures that evolved from a common ancestor such as bones humans, cats, bats, and whales have in common.
What are Homologous Structures?
The scientific name of an organism is made up of these two parts
genus and species
Any inherited trait that increases an organism's chance of survival is known as this.
What is an adaptation?

variations
When one organism's adaptation allows it to copy the appearance of another animal
mimicry
Preserved remains of ancient organisms
What are fossils?
All of the fossils that have been discovered make up this up
fossil record
The concept that organisms who are the best suited to their environment will be the most successful
What is survival of the fittest?
The type of genetic drift happens when a tiny group of individuals splits off from a big main population and moves away to start a brand-new community or island in a new place
Founder Effect
A mistake or change that occurs in the DNA sequence is called a ______________________.
What is a mutation?
The type of genetic drift happens when a big disaster suddenly kills off most of a population.

antibiotic resistance
The law of ________ states that in any sequence of undeformed sedimentary rock layers, the oldest layer is at the bottom and the layers become progressively younger as you move toward the top
Superposition
When an organism completely dies out.
What is Extinction?
Name one evidence of evolution
analagous structures, homologous structures, similar embryos, fossils, DNA analysis
Evolutionists believe that similar orgamisms evolved from a(n)
What is common ancestors?
speciation, new species
Study of how embryos develop similarly
Embryology
When one species changes into two or more different species
Speciation
Body structures on different organisms that are similar in function but did not evolve from the same ancestor (bird wing and butterfly wing)
What are Analogous Structures?
While in the Galapagos Islands, Darwin noticed that the Finches' beak shape had evolved based on the...
food source
The preserved remains of a plant or animal that lived for a relatively short, well-defined span of geologic time and is used by scientists to identify, date, and correlate rock layers- the conodant is an example
