The ideas of descent with modification are based on fossils and the modern organisms he found basically says that genetic changes are inherited by later generations.
Fossils are not found in extrusions and intrusions, such as lava flows and igneous rock formations, because the extreme heat and pressure generated during these volcanic processes usually destroy any organic material present. Fossils are typically found in sedimentary rocks, where the remains of organisms are buried and preserved in layers of sediment over time.
The crust. There are no fossils in the core as the outer core is liquid and no organisms have lived on the inner core.

Fossils. Fossils are the preserved remains or traces of organisms found in rocks or other geological formations. They provide valuable information about past life forms and environments.
No, human fossils are among the rarest type of fossils. Fossils of plants and marine organisms are far more abundant and have been found in greater numbers than human fossils.
99% of all organism who lived once are now extinct, so a list would be more than extensive! Dinosaurs are the big fossils. Mammal fossils are big too. Human and proto-human fossils may be the biggest things in fossils ever.
