Define an Offspring
Product of reproduction; a new organism produced by one or more parents

Yellow beetle and green beetles live in the rainforest canopy. What would you expect to happen to the beetle Population:
The green population of beetles will increase and the yellow population will decrease
100
What is artificial selection?
The process by which humans choose desirable traits during animal breeding and plant breeding.
100
What other term do we use to describe "survival of the fittest"?
Competition
100
Which of the following is NOT a trait that has evolved in Galápagos finches?
A. Beak size and shape
B. Ability to fly
C. Diet
B. Ability to fly
200
Define a Favorable Trait
A trait that is beneficial to an organism and will likely be chosen by natural selection
200
What happened to the populations of peppered moths during the industrial revolution.
The moth populations started out light colored, but then changed to dark as the soot from the factories allowed them to be better camouflaged.
200
Farmers bred broccoli, cauliflower, kale, and cabbage from the wild mustard plant. What is this process called?
artificial selection or selective breeding
200
A farmer breeds cows with longer legs to help them run faster. This is an example of what?
Artificial Selection or Selective breeding
200
True or false. Mutations are not random and can be chosen by people.
False. Mutations are random
300
Define Genetic Variation
Differences that exist within a population or the same species
300
In natural selection, what is fitness?
It is the ability to survive and reproduce in the environment
300
Define Natural Selection
Process by which organisms with favorable traits are able to survive and reproduce better and over time become more common in the population
300
A species of fish changes over many generations to have a thicker scales to survive in colder waters. This is an example of what?
Evolution
300
What would happen to a population of light-colored deer mice if they were moved to a wooded area with dark soils?
They would die off as they do not have a trait to allow them to camouflage in the dark environment.
400
In an arctic environment, which would survive longer: red foxes or white foxes?
White foxes
400
What is an adaptative trait?
A TRAIT that helps an organism to survive and reproduce better in its environment
400
After traveling to the Galapagos Islands, Darwin noticed a lot of variation among beak sizes in Finches. This variation was a result of:
Developing different adaptations in order to survive on particular islands, specific to foods they eat.
400
What were one of the two main organisms that Darwin studied in the Galápagos islands who had large strong beaks were most likely adapted to eating?
Finches and tortoises.
400
How does the environment play a role in natural selection?
It determines which traits are beneficial for survival.
500
What is a change in a gene that results in a new trait?
What is a mutation?
500
What is a change or difference in offspring called?
What is a variation?
500
Can an organism "CHOOSE" to evolve and change?
No, organisms CANNOT CHOOSE to change their genes or traits!
500
What role do mutations take during Natural Selection?
Mutations cause variation in the population and help organisms to be better adapted for changes in their environment.
500
A group of fish have been observed to show changes in mouth structure over many generations. What process is this describing and what might be the cause of the change?
Natural selection. Fish adapting to the food source for survival.
