Please feel free to refine this list and repost it, just please preserve the photo credits and links to photographers.Also, suggestions for improvement on any items is welcome as this is a lot of material over a wide range of scientific fields, so I have certainly bungled some things here.When a species gets split into two groups by a river, mountain range, island, lake, or ocean via earthquakes, floods, droughts, climate change, or continental drift, the two populations will begin to drift genetically.Mutations that reduce an organism’s ability to survive and reproduce will be less likely to end up in offspring.By measuring the ratio of carbon-14 in a younger fossil, scientists can estimate its age.These fossilized bacterial colonies date back 2.7 billion years and may extend 3.4 billion years.There is so much in this world that only makes sense in the light of Evolutionary Theory. Some of these layers are from the decomposition of sediment, others come from chemical precipitation, others from decaying organic matter, and others from volcanic lava.The reason we can see the layers is because they were formed in different ways.

These reasons will work from the general to the specific.

The process of permineralization, where mineral deposits form internal casts of organisms, provides us with a vast quantity of fossils that give us an idea of the different forms life has taken in the past.

You will never find a Neanderthal bone in the same stratum as a Tyrannosaurus rex bone.

Tyronnosaurus rexes weren’t alive at the same time; therefore, their stratum didn’t get laid down at the same time.

Benjamin Franklin saw that there were fossilized sea shells on top of the mountains of Appalachia, some of them imprinted into solid rock, and concluded, “Tis certainly the Wreck of a World we live on!
