Which statements indicate what the fossil record suggests about evolution on Earth? Check all that apply. Humans have only recently existed on Earth. Organisms originally lived only in Earth’s water. Life on Earth started when water formed on Earth. Plants did not have flowers when dinosaurs existed. Multicellular life evolved before complex single-celled life
The fossils are indicators of lot of things about the past of our planet. They are able to provide information about the organisms that lived at a particular time, the climate conditions, the gasses in the atmosphere, the composition of the water etc. The fossils are able to provide information about creating a good timeline for the past, and how, why, and when organisms developed and evolved. That further leads to numerous other clues about the development of the spheres of out planet, or at least part of them.
The fossil records suggest that life on Earth initially developed in water.
Only after the organisms became more complex in the water, and after they managed to influence big changes in the atmosphere, they started to come out and thrive on land.
There have been lot multiple groups of animals that have dominated Earth in part of its geological past, starting with the insects, than sinapsids, dinosaurs, mammals, and the humans most recently as the pinnacle of the mammal lineage.
