Which statement best represents the meaning of the term evolution?
a)
Changes in species toward greater complexity over time
b)
Changes in inherited characteristics of populations over time
c)
The strongest individuals do not survive or produce offspring
d)
Changes in an individual within their lifetime that help them survive
2.
Which of the following do sharks inherit at birth from their parents?
a)
Knowledge of good hunting spots their parents learned during their lives.
b)
Only genetic traits that were helpful, like large teeth or fast swimming speed.
c)
Many of their parents’ genetic traits, whether they were helpful or not.
d)
Changes in their physical bodies, like strong muscles.
3.
Which of the following is the most likely to happen among a population of sharks when there is not enough food?
a)
By random chance, some sharks will get enough food to survive, and others will not.
b)
The sharks that don’t get enough food will likely die.
c)
The sharks will change their DNA and adapt to survive on less food.
d)
All sharks will survive by working together.
4.
Which characteristic would a biologist find most important in deciding which animals are the “most fit”?
a)
The animal that that lives the longest.
b)
The animal that eats the most food.
c)
The animal with the largest number of babies that survive and reproduce.
d)
The animal with that is the strongest and dominates others in the population.
5.
Within a population of dolphins there are differences in the flipper size of adult dolphins. What causes these differences?
a)
Dolphins have lots of different mutations in their genes that occur to help individuals survive.
b)
Random genetic changes within the population lead to differences in flippers.
c)
Changes in the food source cause mutations that change flipper size to help the dolphins swim faster.
d)
Flipper size is not controlled by genes at all.
6.
According to evolutionary theory, why are there similarities in the forelimb structures of the organisms in this image?
a)
All of the vertebrates evolved in similar habitats.
b)
There are no similarities in the structures of the vertebrates.
c)
The vertebrates shared a common ancestor.
d)
The structures of the vertebrates evolved throughout the course of a lifetime.
7.
Over time what might cause one ancestral population of whales to split into three species (like Sperm Whales, Right Whales, and Porpoises) after they became separated in three different oceans?
a)
Whales that were isolated in different oceans changed their own DNA to improve their fitness.
b)
Mutations happened specifically to help different groups of whales adapt to the different oceans.
c)
Variation and selection led to groups that were no longer able to mate with the other groups of whales.
d)
Within one lifetime, the whales adapted to be the most fit in their new environments.
