Which best describes darwin’s studies that led to the theory of evolution? extensive research of an individual organism within a short period extensive research of an individual organism over many years observations and data collected within a short period observations and data collected over many years

the correct answer at least on engenuity is d, observation and data collected over many years. i just took the test

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.

characterization of nanoparticles is a critical step in nanomaterial production as it provides information of dimension, morphology, surface charge, distribution and degree of surface functionalization.
