7 Animals That Evolved at Hyperspeed — Because of Us

The video explores rapid evolutionary adaptations in various species due to human-induced environmental changes. Examples include Cliff Swallows evolving shorter wings to avoid cars, fish becoming smaller due to fishing pressures, mosquitoes adapting to underground habitats, sea snakes developing darker skin to combat pollution, and elephants evolving tusklessness to evade poachers. The video emphasizes that while some species can adapt quickly, not all can, and human responsibility remains crucial.

What adaptation have Cliff Swallows developed to avoid cars?

• Shorter wings for better maneuverability

• Longer wings for better gliding

• Stronger beaks for breaking car windows

• Louder calls to warn other birds

How have fish species like salmon and cod adapted to avoid overfishing?

• By changing their diet

• By developing thicker scales

• By becoming smaller and maturing earlier

• By migrating to deeper waters

What is a significant change observed in the London Underground mosquito?

• It has developed resistance to insecticides

• It has become larger in size

• It prefers mammal blood over bird blood

• It hibernates during winter

How have turtle-headed sea snakes adapted to industrial pollution?

• By developing thicker skin

• By becoming darker to bind heavy metals

• By changing their diet

• By migrating to cleaner waters

What is industrial melanism?

• A process where animals change their diet

• A process where animals develop metallic scales

• A process where animals become darker to bind pollutants

• A process where animals become lighter in color

What led to the extinction of the Edith's Checker Spot butterflies in Nevada?

• Inability to switch back to native plants

• Introduction of a new predator

• Climate change

• Over-collection by humans

Why have tuskless elephants become more common in some areas?

• Due to climate change

• Due to a natural mutation

• Because they are better at finding food

• Because tuskless elephants are less likely to be poached

What is a potential reason for the missing plastic in the ocean?

• It is sinking to the ocean floor

• It is being consumed by evolved microbes

• It is being broken down by sunlight

• It is being eaten by marine animals

What is a limitation of evolutionary rescue?

• It takes many generations to occur

• It is only effective in large populations

• It requires human intervention

• It can only occur in plants

What factor can speed up evolutionary changes in a species?

• Living in a stable environment

• Producing many offspring quickly

• Having a diverse diet

• Having a long lifespan
