Jataka Tales the Mouse Merchant (Amar Chitra Katha)

Gautama was once born a prince, over 2500 years in the past in Lumbini, within the northern a part of India.

However, none of the mice from Armendaris shared any of the mutations that contributed to the dark color of mice from Pinacate.

This approach, which is sometimes called descriptive science, provides information about systems that have not yet been well studied. For example, biologists are now collecting observational data about the precise chemical structure of the DNA in different species of organisms for the purpose of understanding their evolutionary relationships. In other cases, researchers collect experimental data, information that describes the result of a careful manipulation of the system under study. indd 13 tal science, often answers questions about why or how systems work as they do.
