Question

Gentoo penguins present a potential mate with a pebble. Emperor penguins have a specific call and movement that they make to attract a mate. Which type of isolation do these penguins demonstrate?
temporal isolation
behavioral isolation
geographical isolation
anatomical isolation

Answer 1

Behavioral isolation — their species-specific courtship behaviors (pebble-giving, calls/movements) prevent interbreeding by attracting only conspecific mates.
