If someone could give me an example of when developmental homeostasis works in an animal, and when it doesn't.

Thanks!!!

Developmental homeostasis is the ability of an organism to achieve and maintain a stable and functional developmental outcome despite variations in the environment or genetic factors. It ensures that the organism develops into a typical form and structure for its species. However, there are instances when developmental homeostasis may not work as effectively.

Here's an example of when developmental homeostasis works in an animal: In many vertebrates, including humans, the development of limbs follows a predictable pattern. Regardless of genetic variation or environmental influences, a typical limb structure with the correct number and arrangement of bones, muscles, and tendons is formed. This demonstrates the capacity of developmental homeostasis to produce consistent limb development across individuals.

Now, let's consider a case when developmental homeostasis may not work as intended: Consider an animal species that is exposed to extreme environmental conditions, such as large temperature fluctuations during embryonic development. If the environmental cues become too extreme or variable, it can disrupt the normal developmental processes, leading to structural abnormalities or dysfunctional outcomes. In such cases, the developmental homeostasis may not be able to compensate fully, resulting in developmental issues.

It's important to note that while developmental homeostasis generally works well, it is not infallible. Environmental factors, genetic mutations, or disturbances during development can sometimes undermine its effectiveness. Studying such exceptions helps scientists understand the limits and robustness of developmental processes in different organisms.
