Study Notes
Reasons for Reproduction
- There is no mention of "to make money" or "to get food" as reasons why animals reproduce, implying that these are not valid reasons.
Human and Animal Reproduction
- The main difference between human reproduction and that of some animals like fish and insects is that humans have a much more complex reproductive system.
Australian Rabbit Population
- After twelve rabbits were introduced in Australia in 1859, the rabbit population grew exponentially, becoming a significant problem.
Species Extinction
- When a species becomes extinct, it means that the last individual of that species has died, and there are no more individuals of that species left.
- Humans can speed up the process of a species becoming extinct by habitat destruction, pollution, overhunting, and other human activities.
Species Reintroduction
- The California Condor is an example of an animal species that became extinct in the wild in 1972 but was later reintroduced to the wild.
Purpose of Sexual Reproduction
- The purpose of sexual reproduction in animals is to increase genetic diversity and produce offspring with a unique combination of traits.
Population Decline
- If a species of animal is dying faster than young animals are being born, the population will decline, leading to a risk of extinction.
Offspring and Extinction
- The role of offspring in preventing the extinction of a species is to ensure the continuation of the species by replacing dying individuals.
Significance of Reproduction
- The significance of animals reproducing to make new animals of the same species is to ensure the survival of the species and maintain the balance of ecosystems.
