This timeline of the evolutionary history of life represents the current scientific theory outlining the major events during the development of life on planet Earth. In biology , evolution is any change across successive generations in the heritable characteristics of biological populations. Evolutionary processes give rise to diversity at every level of biological organization , from kingdoms to species , and individual organisms and molecules , such as DNA and proteins. The similarities between all present day organisms indicate the presence of a common ancestor from which all known species, living and extinct , have diverged through the process of evolution. More than 99 percent of all species, amounting to over five billion species,  that ever lived on Earth are estimated to be extinct. While the dates given in this article are estimates based on scientific evidence , there has been controversy between more traditional views of increased biodiversity through a cone of diversity with the passing of time and the view that the basic pattern on Earth has been one of annihilation and diversification and that in certain past times, such as the Cambrian explosion , there was great diversity.
Camels in the Bible
What about the claim that camels were not used during Abraham's time?
There is nothing we admire more than self-awareness. Landmark signs are a big tourist attraction - for some reason, people love reading that something happened precisely where they were standing years ago. Perhaps it's their way of feeling like a part of history? Imagine driving hundreds of miles just to see this sign! Totally worth it in our opinion!
Does carbon dating prove the earth is millions of years old?
Most figures are coarse approximations see footnotes for more details :. One of these was a series of buoys, each containing thermometers located ten feet above the water and at one foot below the water. The study found that water temperatures increased on average by 0. As of June , no similar study has been conducted on a global basis. The largest gap between any of the datasets in any year was 0.
The history of Earth concerns the development of planet Earth from its formation to the present day. The geological time scale GTS , as defined by international convention,  depicts the large spans of time from the beginning of the Earth to the present, and its divisions chronicle some definitive events of Earth history. In the graphic: Ga means "billion years ago"; Ma , "million years ago". Earth formed around 4. Much of the Earth was molten because of frequent collisions with other bodies which led to extreme volcanism.
