Basics 2 - Similarity and kinship
  • kinship = verwantschap 
  • Organisms from the same genus                                                     have a lot of similarities
  • example: Lion and a tiger
  • Organisms from the same kingdom have fewer similarities
  • example: Fish and a zebra

Slide 10 - Tekstslide

Species?

  • Organisms that reproduce together and make fertile offspring. 
  • They make babies that can                                                                have babies.

Breed?

Slide 13 - Tekstslide

Evolution
  • Organisms that belong to the same species                            have a lot of similarities
  • Variation
  • Selection - a bird can not see the dark snails so eats the light ones first. The dark shells survive and make babies. Become more common.
  • Evolution

Slide 14 - Tekstslide

Kinship
Animals with a close common ancestor 
are closely related 
  • More closely related means 
       more similarities in DNA                                             overeenkomst in DNA
common ancestor of Tuna, salmander, turtles and leopards
Common ancestor of all these groups
Common ancestor of turtles and leopard
