Adaptations
What is an adaptation?
a trait that increases an organism's ability to survive and reproduce
What is natural selection?
Process by which organisms that are best adapted to their environment are most likely to survive and reproduce
Darwin used scientific evidence to propose explanations for his observations of evolution.
Theory of evolution
The western black rhino no longer exists on Earth. This is an example of...
Extinction
An organism matches its surroundings to hide
Camouflage
The explanation that Charles Darwin provided for how evolution works.
Natural selection
What ship did Darwin travel on around the world?
What is a mutation?
A change in an organism's genetic code
True or False: All variations within a species are also adaptations
False
Only those that increase the organism's chances of survival/reproduction become adaptations over time
The name of the islands where Darwin studied and gathered evidence for natural selection.
Galapagos Islands
What is one thing that Darwin noticed on his voyage around the world?
Differences between organism on South American and in the Galapagos (many possible answers)
What is one way that variations can occur within a species?
Changes of genes/mixing up of alleles when egg and sperm come together OR mutations
Finches' beak size, neck length of giraffes, neck length of tortoises, hardness of shell, color of iguanas
A little child catches a fly and pulls its wings off. The fly actually lives a better life without its wing, but does not pass on this absence of wings to its offspring. Why is this?
"Survival of the fittest" refers to what process studied by Darwin?
Natural selection
Having an extra finger is an example of...
A mutation
Alaskan Wood Frogs can freeze their bodies in the winter in order to survive the harsh cold. This is an example of what?
An adaptation
Give one example of natural selection.
Darwin is known as what?
"Father of Evolution"
Define the term variation AND give one example of this.
Differences between individuals of the same species.
Ex. sea turtles differ in shell color, shell hardness, and ability to swim (multiple answers exist)
