What do animals use to blend into their environment?
Camouflage
When an organism completely dies out.
What is Extinction?
Genetic information that can be used as evidence of evolution between organisms.
What is DNA?
Change in a kind of organism over time; process by which modern organisms have descended from ancient organisms.
What is evolution?
A trait that helps an organism survive and reproduce
What is adaptation?
What characteristic did Darwin observe about the finches on the Galapagos Islands?
Their beaks

What is the fossil record?
Your appendix is an example of what structure?
Vestigial Structure
Body parts that share a common function, but not structure
What are analogous structures?
DOUBLE JEOPARDY
Selection by humans for breeding of useful traits from the natural variation among different organisms
What is artificial selection?
Structures in different species that are similar because of common ancestry.
What are homologous structures?
An ancestral species from which later species evolved
What is common ancestor?
DOUBLE JEOPARDY
A structure that is present in an organism but no longer serves its original purpose (ex. hip bones in whales)
What are vestigial structures?
A mistake or change that occurs in the DNA sequence is called a ______________________.
What is a mutation?
Process by which individuals that are better suited to their environment survive and reproduce most successfully; also called survival of the fittest
What is natural selection?
DOUBLE JEOPARDY
Who is the father of Genetics
Charles Darwin
DOUBLE JEOPARDY
Study of developing embryos used as evidence of evolution.
What is Embryology?
\
A natural process resulting in the evolution of organisms best adapted to the environment ex. fastest, smartest, quietest, loudest, best eyesight, etc.
What is survival of the fittest?
DOUBLE JEOPARDY
A type of graph that shows common ancestry between different species.
