Discuss what you think the word ‘adaptation’ means

Adaptations

Think, pair, share: How are each of these animals adapted to survive?

Adaptation or Variation?

RECAP

Surviving Change

Variation in a population gives those organisms with more favourable features a SURVIVAL ADVANTAGE. When the organisms reproduce, the feature is passed on to its offspring.

-Can you think of any examples of when variation might benefit a species?

-Can you think of differences that are not beneficial? Discuss with the person sitting next to you.

Peacocks with the best display of feathers are more likely to attract a mate.

Some rabbits are resistant to particular diseases and can survive an outbreak?

Albino giraffes do not survive long in the wild. Why?

Adaptation or Variation?

Using everything you’ve learnt this lesson explain the difference between variation & adaptations using your examples to back up your explanation.
