Study Notes

Animal Classifications

  • Four classifications:
    • Cold-blooded/Ectothermic
    • Warm-blooded/Endothermic
    • Diurnal (Active during the day)
    • Nocturnal (Active at night)
    • Crepuscular (Active during dusk and dawn)
    • Vertebrates (Have a backbone)
    • Invertebrates (Do not have a backbone)

Benefits of Backbones and No Backbones

  • Vertebrates:
    • Provide structural support
    • Offer protection for the nervous system
  • Invertebrates:
    • Can move quickly and easily in tight spaces
    • Can thrive in diverse environments

Adaptation

  • Adaptation: The process by which organisms adjust to their environment's conditions over time.

Examples of Adaptations to Climatic Conditions

  • Polar Bear: Thick fur and a layer of blubber provide insulation against cold arctic temperatures.
  • Camel: Long eyelashes shield eyes from sandstorms, while hump stores fat for energy and water reserves.
  • Desert Fox: Large ears radiate heat, allowing the fox to regulate body temperature in scorching deserts.

Evolution

  • Evolution: The gradual change in characteristics of a species over generations.

Reasons for Animal Evolution

  • Adapt to Changing Environments: Variations in the environment (climate, food sources, predators, etc.) lead to advantageous traits.
  • Survival and Reproduction: Individuals possessing suitable adaptations are more likely to survive, reproduce, and pass their traits to offspring.
  • Natural Selection: The process by which organisms with more favorable traits are more likely to survive and reproduce.
