Understanding Viviparity in Mammals
Viviparity refers to the reproductive strategy where embryos develop inside the body of the mother, leading to live birth. Most mammals exhibit this characteristic, making option 'D' the correct statement.
Key Features of Viviparity
- Definition: Viviparous organisms give birth to live young instead of laying eggs.
- Examples: Humans, dogs, and whales are common examples of viviparous mammals.
Comparison with Other Reproductive Strategies
- Oviparity: Some animals lay eggs (e.g., birds, reptiles), which develop outside the mother’s body.
- Ovoviviparity: Certain species like some sharks and snakes retain eggs inside their bodies until they hatch, resulting in live young.
Reasons for Viviparity in Mammals
- Protection: Developing embryos are protected within the mother's body, enhancing survival rates.
- Nutritional Support: The mother provides direct nourishment and oxygen through the placenta (in eutherian mammals), ensuring optimal development.
Exceptions to Consider
- While most mammals are viviparous, there are exceptions like monotremes (e.g., platypus, echidna) that lay eggs.
Conclusion
The prevalence of viviparity among mammals highlights their evolutionary adaptations for nurturing and protecting offspring, which is pivotal for species survival. This understanding reinforces why option 'D' is indeed the correct statement among the provided options.
