Biological Adaptation

Front

What is biological adaptation?

Back

Biological adaptation is when a species changes over time to better survive in its environment.

Front

What can scientists infer from fossils?

Back

Scientists can infer that certain conditions existed in the past, such as water covering an area where a fossil was found.

Front

What do embryos of vertebrates look like in early stages?

Back

In the early stages of development, most vertebrate embryos look very similar.

Front

What features do vertebrate embryos possess in early development?

Back

Vertebrate embryos possess gill slits and tails during early development.

Front

What are the oldest fossils found in geological layers?

Back

The oldest fossils are found closest to the bottom of geological layers.

Front

How do adaptations help species survive?

Back

Adaptations help species survive by allowing them to better fit their environment, find food, and avoid predators.

Front

What is an example of a physical adaptation?

Back

An example of a physical adaptation is the thick fur of polar bears, which helps them stay warm in cold climates.

Front

What is a behavioral adaptation?

Back

A behavioral adaptation is a change in behavior that helps an organism survive, such as birds migrating to warmer climates.

Front

How do fossils provide evidence of evolution?

Back

Fossils provide evidence of evolution by showing how species have changed over time and how they relate to each other.

Front

What is the significance of gill slits in vertebrate embryos?

Back

Gill slits in vertebrate embryos indicate a common ancestry among different species, suggesting evolutionary relationships.
