PhET Natural Selection

In the PhET simulation of natural selection, the species that was evolving was

• wolves

• rabbits

• plants

• seasons

Genetic variations could be created in what rabbit traits? (select all that apply)

• shape of ears

• fur color

• ability to hop

• length of teeth

NGSS.MS-LS3-1

The variables in the environment that could be manipulated were (select all)

• season (color of ground)

• amount of rain

• predators

• type of plant food

Predict what will happen to the rabbit population in this environment.

• The rabbits will become extinct.

• Rabbits with brown fur will survive and reproduce more than rabbits with white fur.

• Rabbits with white fur will survive and reproduce more than rabbits with brown fur.

• Rabbits with big teeth will survive and reproduce more than rabbits with small teeth.

What is the selecting factor in the environment?

• The type of food

• The amount of food

• The predator (wolves)

What is the survival advantage of having brown fur?

In this picture, the selecting factor in the environment is

• fur color

• predator

• tough food

• long teeth

NGSS.MS-LS2-4

In this picture, the genetic variation in the rabbit population that has a survival advantage is

• fur color

• predator

• tough food

• long teeth

NGSS.MS-LS1-5

In the simulation, which variation had no advantage but was a random mutation

• fur color (brown or white)

• ear type (straight or floppy)

• teeth (long or short)

In this scenario, the rabbit population will evolve by

• increasing the percentage that have white fur ONLY

• increasing the percentage that have long teeth ONLY

• increasing the percentage that have white fur and long teeth

• increasing the percentage that have white fur, long teeth and floppy ears
