The phrase "Survival of the Fittest" would best describe...
Natural selection
Artificial selection
Selective breeding
None of the above
Which is not true about natural selection?
There must be diversity in the population.
It is driven by natural processes like predators or weather conditions.
Humans are involved and can select the most desirable organisms.
Predators, geological activity, and weather can all have an impact on organisms.
What is one problem with
artificial selection?
It takes thousands of years.
It removes diversity and bad traits can surface.
It promotes biodiversity of the species.
It can only happen once a year.
What changed in the environment that caused the white moths to not pass on genetic information to offspring?
The factories put smoke into the air, polluting it
The factory's smoke left the trees black and the white moths were eaten.
The white moths were the weakest
The black moths were the strongest
Which is NOT true of natural selection?
It takes place over a relatively long period of time.
The process happens due to environmental activity.
Excessive warmer temperatures in a region have caused rabbits with longer fur to slowly disappear.
It takes place over a relatively short period of time.
A green rat snake that lives in the grass and a brown rat snake that lives in the desert is a form of ______________.
Human Genetic Modification
Selective Breeding
Natural Selection
Artificial Breeding
Which is a result of selective breeding?
Large seedless watermelons that
consumer demand.
Oranges that are all different sizes and colors.
An insect that can carry ten times its body weight.
A bird that catch prey with its beak.
Which statement is incorrect
about natural selection?
A single organism can adapt to a cold
environment by growing longer hair.
Over time organisms with longer hair will survive better in cold environments
Humans are not involved in the natural selection process
The offspring of each generation will likely be more adapted to the environment.

What are the most studied animals in the galapagos?
Finches
Turtles
Tortoises
Lizards
What is the advantage of having different shaped beaks?
To look different from other species.
To protect itself against predators.
To protect itself against prey
To be able to eat the food readily available in the environment.
The theory of evolution by natural selection means that what is changing over time?
The inherited traits of a population.
Hair color and eye color
The acquired traits of a population.
Attractive features.
Why are advantageous traits more likely to be passed onto offspring?
Because they come from recessive alleles.
Because they are more likely to survive and reproduce.
Because the trait is an acquired phenotype.
Because they come from dominant alleles.
What is artificial selection?
The death of every member of a specie
The human practice of breeding animals or plants that have certain desired traits
A change in the structure or amount of the genetic material of an of an organism
