Fossil record provides evidence of evolutionary change from "summary" of The Structure of Evolutionary Theory by Stephen Jay Gould
The fossil record stands as the most tangible document of evolutionary history. Fossils provide us with a window into the past, revealing the organisms that once inhabited our planet and the changes they underwent over millions of years. Through careful examination of these ancient remains, scientists can trace the evolution of species, observe transitional forms, and understand the mechanisms driving biological change. The true power of the fossil record lies in its ability to capture snapshots of past life forms at different points in time. By comparing fossils from various geological layers, researchers can discern patterns of change within and between species. For instance, the gradual transformation of horse ancestors from small, multi-toed creatures to the large, single-toed equines we know today is beautifully illustrated through the fossil record.
