Changing Traits for Adaptation

The video explains how inherited traits and instincts in animals can change over time through adaptation and evolution, allowing them to better survive in their environments. It highlights specific examples, such as polar bears adapting to Arctic conditions with white fur and thick paws, and jackrabbits adapting to desert conditions with large ears and light-colored fur. These adaptations enhance their chances of survival by making them better suited to their respective environments.

What are inherited traits?

• Behaviors taught by other animals

• Learned behaviors from the environment

• Physical characteristics or instinctive behaviors passed from parent to offspring

• Random mutations in animals

How have polar bears adapted to their Arctic environment?

• By living in large groups

• By evolving white fur and thick paws

• By learning to climb trees

• By developing long tails

Why can polar bears swim long distances?

• They can close their nostrils to prevent water entry

• They are taught by their parents

• They have gills like fish

• They have webbed feet

What adaptation helps jackrabbits cool their bodies in the desert?

• Dark skin

• Large ears

• Thick fur

• Short legs

How do jackrabbits escape predators?

• By burrowing underground
