Macroevolution (developmental genes (change in gene sequence (example…

- - - - Artemia Ubx gene
        
        resulted in different gene (Drosophila Ubx)
  - - - threespine stickleback fish
        
        marine species have spines on lower surface, lake species don't have spines
        
        both have Pitx1 gene but regulation of this gene differs in each species
- - - - empty spaces and survivors adapt to fill vacant spaces
    - - seeds, armored body covering
    - - can provide new sources of food
- - - - movements in the mantle cause the continents to move slowly over time
  - - - changes types of organisms in community (affecting interactions)
