Deep Time : A History of the Earth - Interactive Infographic Life on the planet started astonishingly early. The first living organisms, in the current model of evolution, are thought to be Prokaryotes1. The oldest known fossilised prokaryotes have been dated to approximately 3.5 billion years ago, only 1 billion years after the formation of the Earth's crust. Eukaryotes2 are more advanced organisms with complex cell structures, each of which contains a nucleus. Although incredibly hard to determine their origin, they are thought to have developed 1.6–2.1 billion years ago, although some research2 suggests eukaryotes being present even earlier than this.

A large percentage of geography experts now consider the long-established continent of Australia to be more accurately defined as Australia/Oceania. Collectively it then combines all of Australia, New Zealand, Papua New Guinea, as well as the thousands of coral atolls and volcanic islands of the South Pacific Ocean, including the Melanesia and Polynesia groups. Oceania also includes Micronesia, a widely scattered group of islands that run along the northern and southern edges of the Equator.
Myrmedrome - A real ant colony simulator MYRMEDROME is an ant colony simulator which tries to imitate the ants’ life as well as possible without introducing artificial effects. The simulation is based on the fundamental principle that each ant is not enough intelligent to understand it lives in a complex community, nor it is able to organize tasks in its colony. Therefore, each ant lives and works following some simple rules interacting (unaware of it) with the others by chemical signals. Animal Adaptations Being able to adapt is a matter of life or death. Animals who can't adapt - die! For animals, adaptation is the idea that animals have developed features that help them to survive and thrive where they live. Some adaptations are purely physical.
Classification Why do we classify things? * Classification provides scientists and students a way to sort and group organisms for easier study. * There are millions of organisms on the earth! (approximately 1.5 million have been already named)
