The ability of an individual to survive and reproduce is known as this.
What is fitness?

A mistake in the genetic code of a section of DNA is known as a ______________.
mutation
200
Similar structures that evolved from a common ancestor such as bones humans, cats, bats, and whales have in common.
Homologous Structures
200
Scientist who added to Darwin's theory by clearing up how traits were passed down to offspring through his pea plant experiments.
Mendel
200
Any inherited trait that increases an organism's chance of survival is known as this.
What is an adaptation?
200
Darwin was from the 1800's. What part of modern science did he lack knowledge of in order to better explain how traits were passed down from parent to offspring?
genetics and DNA
200
When organisms of the same family begin to look different due to changes, which can eventually lead to speciation
What is divergent evolution
300
Preserved remains of ancient organisms
What are fossils?
300
This term refers to different traits and alleles within a population.
What is variation?
300
The concept that organisms who are the best suited to their environment will be the most successful
What is survival of the fittest?
300
What are 2 of the 4 conditions of natural selection?
Inheritance, Variation, Overproduction/competition, Differential Survival
300
The "parent" species from which two or more separate species evolved is known as _____________.

What trait did Darwin observe about the finches on the Galapagos Islands?
Their beaks!
400
The concept of humans selecting desired traits in species.
What is Artificial Selection?
400
Structures with similar functions but are not similar in origin like a butterfly wing and a bat wing. These are not proof of a common ancestor but proof that evolution can occur
Analogous Structures

The bones of this ocean animal (mammal) have been examined and proven that their ancestors at one time walked on land. They are distantly related to the hippopotamus.
What is a whale?

When fossils are found in the same rock strata, or layer, what does that say about the organism?
They died at the same time
500
Which term refers to the process by which individuals that are better suited to the environment survive and reproduce therefore passing down their genes to their offspring?
Natural Selection
500
The concept that members of each species are seeking the same food, space, and other necessities is known as this.
What is competition?
500
The embryos of different organisms look similar because...
the developed from common ancestors

What are the 3 of the 5 evidences of evolution?
Structures, DNA, Fossils, Embryos, and geography
