Impact of Environmental Changes on Species

The video explores the concept of natural selection through the fictional species 'fuzzies'. It describes how environmental changes, such as flower color dominance and temperature shifts, affect the survival and reproduction of fuzzies. Over time, these changes lead to the extinction of fuzzies due to a lack of suitable adaptations. The video highlights the role of genetic diversity in species survival and uses the fossil record as evidence of extinction and evolution.

What determines the color of a fuzzy?

• The climate they live in

• The genes in their DNA

• The type of flowers they eat

• The predators they avoid

Why did blue fuzzies initially have an advantage?

• Blue flowers were more common

• They reproduced faster

• They could survive without flowers

• They were better at avoiding predators

What caused the pink fuzzy trait to become favorable?

• A decrease in predator population

• An increase in pink flowers

• A change in diet

• A genetic mutation

How did rising temperatures affect the flower population?

• It led to a decline in flower populations

• It caused all flowers to thrive

• It had no effect on flowers

• It increased the number of flowers

What advantage did green fuzzies have as flowers declined?

• They were immune to predators

• They could camouflage better

• They needed less food

• They were faster

What happened to the blue fuzzy trait as the environment changed?

• It became more common

• It was lost

• It mutated into a new color

• It became dominant

Why did the pink fuzzies eventually go extinct?

• They couldn't compete without flowers

• They evolved into a new species

• They were hunted by predators

• They migrated to a new area

What is a major factor in the extinction of species?

• Too much genetic diversity

• Overpopulation

• Inability to adapt to environmental changes

• Lack of food

What percentage of species that once existed have gone extinct?

• 99%

• 10%

• 50%

• 75%

What provides evidence of past extinctions and evolution?

• Weather patterns

• Fossil record

• Animal behavior

• Plant growth
