Adaptation

ADAPT OR DIE!

• As the world is changing species must use many strategies to stay healthy and preserve their ability to leave healthy offspring

• Who are best adapted?, It isn´t always the strongest, nor the most beautiful. Only those that are best able to leave healthy offspring.

ADAPTATION

• Biological definition:• Any alteration in the structure or function of an organism or any of its parts

that results from natural selection and by which the organism becomes better suited to survive and multiply in its environment.

Different kinds of adaptation

• Physical• Changes in the body

• Physiological• Cytochrome p450 http://www.ncbi.nlm.nih.gov/pubmed/9569642

• Behaviour• Migration In time or place

• Changing of resources to survive

Physical adaptations are evident in the body

Behavioral adaptations are not so evident in the body

• Terrestrial (land) Iguana• Iguanas from galapagos Island

Extreme ecosystems need extreme adaptations

• Extreme dryness • Adaptations to harvest water from

air in desert conditions• The fog basking beetle

Is it true? Being together is useful to keep penguins warm?

Complete a design practical to determine how the behavioural adaptations seen in Emperor penguins allow them to survive in their environment. In this case the penguin will be represented by a boiling tube of warm water and the environment will be represented by an ice bath.Remember that your design MUST reflect the situation observed. You cannot simply wrap the boiling tube in tin foil or Styrofoam.
