Adaptations I
What is an Adaptation?
An inherited trait that improves survival and reproduction.
What is camouflage?
When an animal blends into it's surroundings.
What is Natural Selection?
The process of becoming more successful than others.
What is survival of the fittest?
Organisms best adjusted to their environment are the most successful in survival and reproduction.
Give an example of a learned behavioral trait.
Teacher checks
What is migration?
When animals move North or South during Winter.
What is hibernation?
When animals sleep through Winter.
What is evolution?
Evolution is the process in which populations gradually change over time.
What is the Charles Darwin theory?
The theory that animals have different traits for better survival.
Give an example of an acquired physical trait.
Teacher corrects. Scar, tan, dyed hair.
What is a behavioural adaptation?
Something an animal normally does to survive.
What is a structural adaptation?
The way an animal is built to survive it's environment.
What is artificial selection?
When humans breed specific plants or animals for desired traits.
Sexual vs asexual reproduction difference?
Sexual reproduction has parent, asexual reproduction has no parent.
Give an example of an organism that uses "overproduction" as a method to maintain the population.
Spiders, turtles, fish
What type of adaptation is migration?
Behavioural adaptation.
What type of adaptation is hibernation?
Behavioural adaptation.
Who is Charles Darwin?
Known as the "father of evolution." Created the theories of evolution and natural selection.
What is genetic variation?
The differences passed on to offspring from parents in the same species.
2 learned behaviors in organisms: 1) when a baby organism follows the first moving thing it sees 2) when an organism learns to respond to a specific event with a specific action
Imprinting and Conditioning
What does the eye placement of an animal determine?
Whether it is prey or predator.
In our Natural Selection simulation with bunnies, which were the 3 traits that helped the bunnies survive against predators and changes to their environment?
Name the 4 steps of Natural Selection
Overproduction, Genetic Variation, Competition (struggle to survive), Successful Reproduction
How is natural selection related to genetics?
If a trait is advantageous and helps the individual survive and reproduce. Or, Genetic variation.
Give an example of a specific organism changing through natural selection.
Teacher corrects. (Peppered moth, giraffes, bunnies)
