Fossils are the preserved remains of an animal or plant in a rock. Many of the fossils discovered so far are the ancestors of organisms that are alive today. The study of fossils is called paleontology. Much of what we understand about evolution comes from studying fossils. When organisms die, t
The theory of evolution states that individuals within a species show wide degrees of variation, and those individuals with characteristics best suited to their environment are more likely to survive and reproduce. This theory grew from studying the variations and similarities in living animals and
The study of finches led to the development of one of the most important scientific theories of all time. In December 1831 a naturalist called Charles Darwin boarded the HMS Beagle, bound on a surveying voyage of South America. Whilst the ship and crew carried out coastline surveys, Darwin was fre
In this video segment from NOVA: "Judgment Day: Intelligent Design on Trial," paleontologist Neil Shubin recounts a fossil discovery that added another compelling piece to the body of evidence that supports evolution. Shubin's find of a well-preserved skeleton, a "fishapod," represents a transitiona
Paleontologists estimate that around 380 million years ago, there were fish with pectoral fins that already had finger-like bones. And from those, the limbs of vertebrates evolved. The skeleton of these limbs follows the same basic blueprint: Authors: ZDF/3sat/Marco Polo Film AG/Herbert Ostwald/Hol
How are fossils actually formed? And why are they formed in some places and not in others? Author: ZDF/Terra X/Spiegel TV/Jens Nicolai/Oliver Roetz/Hauke Ketelsen/Richard Sako Translation and dubbing: alugha Click here to see more videos: https://alugha.com/TerraX

Fossils discovered within rocks led scientists to begin to change their ideas on the creation of life on earth. JOIN our platform at www.fuseschool.org This video is part of 'Chemistry for All' - a Chemistry Education project by our Charity Fuse Foundation - the organisation behind FuseSchool. The
Learn about the evolution of Earth's moon, from its initial formation to its current state, in this video from NASA. Real satellite imagery, as well as simulations, explore how the Moon has changed over time. The video looks at how the Moon likely formed about 4.5 billion years ago, how impacts from
When a plant or animal species that once lived stops existing entirely, we say that that species has become extinct. Why do certain species of plants and animals sometimes become extinct? According to the theory of evolution, individuals of the same species show a range of variations. Some individ
In nature, all organisms compete with each other for resources in order to survive. Competition between members of the same species is what makes organisms evolve. This theory of competition and ‘survival of the fittest’ is called Natural Selection, and was originally proposed by Charles Darwin i
The way we grow and develop in the womb is controlled by our DNA. Small sections of DNA, called genes, carry the code telling the body how to build itself. Usually this works fine, but sometimes those genes carry mistakes in their code. These mistakes, known as mutations, may have no effect, they ma
