Observations and data collected over many years

Explanation:

Darwin was the first scientist to offer scientific evidence on the evolution of species, through natural selection. However, he did not make this discovery overnight, or for a few hours. In order for Darwin to establish the theory of evolution, it was necessary for him to take a trip across five continents, observing the most varied number of species. In addition, he only created the theory after doing several experiments over a long 20 years.

For this reason, we can say that what best describes Darwin's studies that led to the theory of evolution are observations and data collected over many years.
