” The shells were deposited in layers on the Ocean floor over millions of years, layers that would be violently broken up and rippled into a mountain range 480,000,000 years ago by a catastrophic earthquake.
When molten rock hardens into a solid, the uranium-238 within it begins to decay.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.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.Jump To: Age of the Earth and Its Fossils Genetics Comparative Anatomy Transitional Fossils Convergent Evolution Adaptations Vestigial Traits Artificial Selection Evolution in Action Sexual Selection And The List Goes On…
These reasons will work from the general to the specific.
Cynognathus, a Triassic land reptile, fossils are found in South America and Africa.
The Triassic era was between 250,000,000 and 200,000,000 years ago.
Layers are laid down on top of each other, with the bottom layers laid down first and the top layers laid down last; therefore, the layers on the bottom are the oldest and the ones on the top are the youngest.
Dinosaur footprints, slug footprints, Australopithecus footprints and other footprints on top of any layer in the strata means that layer was at the top of the stack long enough for something to walk on top of it before it got covered by subsequent layers and hardened into solid rock.
Mutations that give an organism a survival and reproductive advantage will be more likely to show up in offspring.
