evolution

• What does variation between species refer to?

  Differences among distinct species
• What does variation between individuals of the same species mean?


  Diverse traits within a species
• How does genetic diversity affect competition among organisms?


  It allows some organisms to compete better
• What are the factors that differentiate species variation from individual variation?


  • Species Variation:
  • Different characteristics among species
  • Species-wide competition
  • Determines species survival

  
  

  • Individual Variation:
  • Diverse traits within a group
  • Intra-species competition
  • Influences individual fitness
• What is an example of individual variation in rabbits?


  Some rabbits are faster than others
• Why might faster rabbits survive better?


  They can escape predators more easily
• What happens to rabbits with better camouflage?


  They are less likely to be eaten
• How does variation affect the survival of rabbits?


  It allows some to live longer and reproduce
• What can happen if the environment changes for a species?


  Some individuals may become less adapted
• What is an example of environmental change affecting survival?

  Brown rabbits becoming visible in snow
• What are the impacts of environmental changes on organisms?

  • Climate Change:
  • Alters habitats
  • Favors organisms with specific tolerances

  
  

  • Invasive Species:
  • Introduces new competition
  • Affects native populations

  
  

  • Habitat Loss:
  • Reduces resources
  • Decreases individual fitness
• What is heredity?


  The process of passing genetic information
• How does heredity determine traits?


  Through DNA replication and cell division
• What is the impact of competition on species survival?

  It determines which species survive
• How does individual fitness relate to genetic diversity?


  Higher genetic diversity can improve individual fitness
• What is the impact of environmental changes on species competition?


  It can alter competition dynamics among species
• How does genetic information determine traits like eye color?


  It is passed from parents to offspring
• How does heredity relate to traits like height?


  Traits are inherited from parents through genes
