  • adaptation and variation
    • species adapt to their environments
    • species are a group of organisms that can breed together to produce fertile offspring
    • individuals of the same species have differences
    • adaptations mean species are more likely to survive
    • the cactus is well adapted for hot dry desert environments
    • fish are adapted to aquatic environments
    • differences in species is called variation
    • some variation is genetic
    • mutations can be caused by chemicals, radiation or mistakes during cell division
    • variation can be passed onto offspring
