  1. Life spontaneously arose 4 billion years ago as bacteria-like cells…. … and today it has evolved to many complex and diverse forms.

  2. It took life 4 billion years or 1,460,000,000,000 days to evolve into… • 10-100 species • To live in every available environment on earth, form the water, land, to air, the deepest regions of the oceans, on volcanic vents, to Antarctica. • For complex ecosystems to form; rainforests, coral reeves, savannah and ... • For an animal to reach 200 tons; Blue Whale • For the creation of an amazingly complex and innovative animal to be born and to question life itself; Humans

  3. If it took life 1,460,000,000,000 days to evolve into such diversity… … how much evolution can happen in just 4 days?

  4. We will test this week just how fast evolution can occur.

  5. Examples of rapid evolution • Darwin’s finches; doubling of beak size in just years.

  6. Examples of rapid evolution • Drug resistance in disease; antibiotic resistance in hours.

  7. Examples of rapid evolution • Cichlid fish; 500 new species in just 24,000 years
