im going to try put this as clear and less sciency as possiable. So bare with me.
When a species elovs into an adapted species, this new trait is a benefit to keep it alive or improve its life. So when a fossil is found it will have simlaries with a modern day animal that it has evoled into.
For example a fossil is found with a hooked beak, dietary sytem and feet like a chicken. If nothing else has more simlaties with it, it will most likely a species that has evolved into chickens. This is not always a relieable way of comparion but it gives a good anylise of the animal.
Hope this helped somewhat. And p.s. look through this yourself children for spelling mistakes before you copy and paste it as ur homework. LOL i know the tricks.
Evolution
Directed evolution
By examining fossils and by determining their relative and absolute ages, scientists have collected evidence that supports the theory that species changed over time.
Scientists leverage genetic evidence, like DNA sequences, to classify organisms based on evolutionary relationships. By comparing genetic similarities and differences, they decipher ancestral connections, constructing phylogenetic trees that depict species divergence and common ancestry. This method, termed molecular systematics, revolutionizes taxonomy by revealing hidden relationships, redefining classifications, and aiding conservation efforts. Curious to explore more?

A scientists uses an organisms genetic and shared physical traits.
Scientists use mainly fossils.
Scientists use a variety of tools and techniques to study prehistory, including archaeology, carbon dating, genetic analysis, and the examination of fossils. By analyzing these sources of evidence, scientists can reconstruct timelines, understand human behaviors, and piece together a more comprehensive picture of our ancient past.
Scientists use a variety of evidence to study early migration, including genetic analysis of modern and ancient populations, archaeological artifacts, isotopic analyses of human remains to trace diet and geographic origin, and studies of ancient pollen and plant remains to reconstruct past environments. By combining these different lines of evidence, scientists can piece together the story of how humans migrated and settled around the world.
Scientists use a variety of evidence to study migration, including tracking animals using GPS technology, studying changes in hormone levels, analyzing isotopes in tissues, and conducting genetic analyses. They may also observe behaviors such as flocking patterns or migration routes to better understand the movement of animals.
Scientists use a variety of evidence to study prehistoric times, including fossils, geologic strata, archaeological artifacts, DNA analysis, climate data, and isotopic analysis of elements found in ancient specimens. By examining these different types of evidence, scientists can reconstruct past environments, track the evolution of species, and understand human history.

Scientists use a genetic marker to determine the success of a transformation. Genetic markers will change if the transformation has succeeded.
to study dolphins
the scientists had empirical evidence waiting to be answered
whattools do scientist use to study meteors
Scientists use an electron accelerator :)
