THE ARMS RACE - Coggle Diagram

- - - - eg. plants
        
        creeping plants fought for light by growing over each other
        
        mosses invent the stem - others must also get stems
        
        vascular plants can get tall
- - - - then new mutation for more specific preference will spread
        
        etc etc etc
    - - preference changes
      - selection is opposed by other factors
        
        at some point increased mortality due to difficulty getting away from predators negates any advantage
- - - - need big brains to deal with other members of same species
      - cooperation
      - outwitting rivals
    - - cooperative hunting, foraging
      - language
      - sophisticated tool use
      - cooperative attack and defence
      - cultural evolution
- - - - colour changing
      - matching background colours
      - countershading
      - dazzle camouflage
      - mimicry
  - - - mineralised armour evolved multiple times in different lineages
      - shells are anti predator adaptations
        
        diversity of shell predators peaks in tropics
        
        most shell predators are also defended by armour
      - mor elaborate armour = more sophisticated predators
- - - - big compound eyes
      - grasping appendages armed with spines
      - swimming appendages to pursue prey
    - - trilobites
      - brachiopods
      - halkeriids
  - - - predators evolve crushing teeth and claws, ability to pry open armour
- - - - antibodies
      - inflammatory responses
      - ability of WB
