This involves population and individuals
What is Evolution?
100
The survival and reproduction of the organisms that are genetically best fit for their environment
What is the definition of Natural Selection?
100

The beaks of finches were different because

the change in environment

100
The hip bones of a dolphin and the tailbone of a human
What are Vestigial Structures?
100
The ability of an organism to survive and reproduce in its environment.
What is Fitness?
200
A theory (explanation) supported by evidence for how populations change over time
What is evolution?
200

Species adapt to their enviornment through

Natural selection

200
A variation in an organism that helps it survive
What is Adaptation?
200
An example of a structure that is homologous to a cat’s paw.
What is a Dog’s paw, human arm, bat wing, whale flipper

Macroevolution

formation of a new species
300
Charles Darwin
Who is the father of Evolution?
300
The name of the islands where Darwin studied and gathered his evidence on Natural Selection
What are The Galapagos Islands?
300

In whales, the pelvis and femur bones hae no function. This is an example of

Vestigial structures

300
Body parts that share a common function but have a different structure
What is an analogous structure?
300
A group of organisms that look alike and can reproduce
What is a species?
400

The fossil record proides evidence that

Older species gave rise to more-recent species

400

For what reason did Darwin conclude the Galapagos finches had different sized beaks

Changes in the environment

400

The presence of the vestigial pelvic bones of a baleen whale and vestigial hind limb bones of the extinct whale show

Whales evolved from four-legged animals

400
Human tail bone and the appendix are examples of

Vestigial structures

400

Microevolution

Changes in genes

500
Two different organisms are alike, they share this in their bloodline
What is a Common Ancestor?
500

What is the mechanism of evolution

natural selection

500

Adaptations help an organism survive, which increases the ability of the organism to

reproduce

500
In embryology, the embryos are very similar to each other
What is a common ancestor?
500

When a population changes over time

What is evolution?
