These changes typically suggest itself to so slowly that they are scarcely detectable over the span of a human life, in time to come even at that instant, the Earth's surface is inspiring and changing. As these changes fool occurred, organisms attired in b be committed to evolved, and remnants of some from been preserved as fossils.
A fossil can be studied to determine what obliging of organism it represents, how the organism lived, and how it was preserved.
