Incubation is the process of maintaining optimal conditions for the development of eggs or embryos. In nature, many birds, reptiles, and some fish incubate their eggs by keeping them warm, often by sitting on them or using environmental heat. This warmth is crucial for the growth and development of the embryos inside the eggs. In a broader context, incubation can also refer to the nurturing of ideas or projects in a supportive environment. For example, business incubators provide resources and mentorship to startups, helping them grow and succeed. This type of incubation fosters innovation and entrepreneurship.
