Fact or Crap?• If you believe that the information given

on the slide is truthful & accurate simply write FACT on your whiteboard

• If you believe that the information given on the slide is NOT accurate information write CRAP on your whiteboard, AND THEN WRITE A CORRECT STATEMENT!

Fact or Crap?• The 4 Principles of Natural Selection are:–Variation–Mutation–Selection–Overproduction

Fact or Crap?

• Evolution can be geological or biological

Fact or Crap?• A cheetah preying on the weakest

member of the antelope herd is an example of Darwin’s idea of

Survival of the Fittest

Fact or Crap?• A good example of evolution

would be the leaves on the trees changing every season

Fact or Crap?

•Most living things leave a fossil behind

Fact or Crap?

•Phenotype means that an organism’s DNA mutates

more easily

Fact or Crap?• Vestigial structures are things that may have been useful to an organism’s ancestors, but are no

longer used

Fact or Crap?

• Similar development of embryos in different

species is evidence of a common ancestor

Fact or Crap?• Analogous structures mean

that they have the same structure and same function

Fact or Crap?

•Biological classification can also be referred to as

taxonomy

Homologous, analogous or vestigial?

• Homologous: – same structure, different function– evidence of a common ancestor

• Analogous:- different structure, similar function- evidence of common environmental demands

• Vestigial:– remnants of ancestor, no longer useful

Homologous, analogous or vestigial?

Homologous, analogous or vestigial?

don't nurse their young

don't have hair

skeleton made of bonego to the surface and breathe atmospheric air in through their blowholesdo nurse their youngdo have hair — they are born with hair around their "noses"

Homologous, analogous or vestigial?

• Wisdom Teeth

Homologous, analogous or vestigial?

Homologous, analogous or vestigial?

• Remnants of a 3rd eyelid

The Challenge: Homologous, analogous or vestigial?

• Leaves on an oak tree

• Leaves on a gingko tree

Evolutionary trees• That last example was hard to figure

out…how would we ever know they have a common ancestor?

Reading Evolutionary trees

Speciation• These speciation events in the evolutionary

tree allow for our planet to have greater biodiversity?

• What is biodiversity?

Station review• Find out the answer to that question and

more!

• Visit each of the 5 stations and write the answers to each of the questions on page 9 of your notebook!
