  one another, it may be more likely to see food directly in front of them.

Open Ended

Why might different species in the same environment share some traits?

The video mentioned that some traits are influenced by environment.

For example, if a person is born with the potential to grow very tall, but they don't get proper nutrition, it is unlikely that they will be tall.

Environmental Example

Scientists think that poison dart frogs get their poison from the insects they eat. It is not simply something they are born with.
