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.
