Archeologists.
Scientists study stellar spectra to learn about their properties such as temperature, chemical composition and relative chemical abundances, radial velocity, rotational speed etc.
Earth's magnetic reversals are recorded in rocks that contain magnetized minerals, such as iron-bearing minerals like magnetite. When these minerals solidify and align with Earth's magnetic field, they preserve a record of the magnetic field at that time. Scientists can study these rocks to determine the timing and duration of past magnetic reversals.
Scientists study fossils, ancient tools, and DNA to learn more about early humans. By comparing and analyzing these sources of evidence, scientists can piece together information about the behavior, lifestyle, and relationships of our ancestors.
they learn by going to a good school and study the stars and planets
Scientists study seismic waves from earthquakes to learn about the layers of the Earth. By examining how these waves travel through the Earth, scientists can infer information about the composition and structure of the various layers beneath the surface.
Their bone structure from fossils and their morphology
