Charles Darwin
The pelvic bone of whale is an example of what structure?
vestigial structure
The process where organisms with favorable traits survive and reproduce more than others
Natural Selection
Name a form of evidence for evolution
Fossils, Homologous Structures, Embryology, or Vestigial Structures
Darwin noticed that finches on different islands had different beak shapes based on what?
Food source or Environment
This famous naturalist traveled to the Galapagos Islands and proposed the Theory of Evolution.
Charles Darwin
Some individuals in a population possess traits or characteristics that make them better suited for their particular environment. What happens to these traits with each new generation?

Charles Darwin
What do we call structures found in different species that are similar in function but that evolved independently? For example, the wings on a butterfly and on birds.
Based on the DNA sequences shown, which animal is more closely related to the mouse?
Rabbit- TTATCGA
Dog- TCATCGA
Mouse- TTAACGA
Bat- TCATCGA
Rabbit
Study of embryos of various organisms to show a common ancestor because of similarities in development
The selective breeding of organisms by humans for specific desirable characteristics is referred to as?
What are the 5 points of darwins theory on natural selection.
Adaptation
Variation
Overproduction
Time
Inheritance
As part of a simulation of evolutionary process, a teacher drops 500 red and 500 green jelly beans on green grass. The red and green jelly beans represent individuals of the same species. Students represent predators and pick up as many jelly beans as possible in 30 seconds. Which prediction is most accurate?
Which of the fossils are the oldest? The ones closest to the surface or the ones farthest away from the surface?
Farthest away
A structure that is similar in apperance and comes from a common ancestor.
Homologous
Maria wanted to rid her home of cockroaches. She applied pesticide and after one day, she found many dead cockroaches. Days after, she observed a few live cockroaches. She reapplied the pesticide, but she continued to see some live cockroaches. What best explains the continuing presence of live cockroaches?
Where island did Darwin write most of his book about "On the Orgins of Species."
The Galapagoes Islands
What is a heritable change in an organism that allows for it to survive in its environment?
Adaptation
Why so pesticides not work on all bugs?
Variability allows for natural resistance
A structure that has the same job but came from a different ancestor.
Analogous
What is the term for a measure of the ability to survive and produce the most offspring?
fitness
What did Darwin call the natural differences in the finch population?
Variations
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
