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
Learn how the analysis of rock layers and ocean sediments supports the theory that rapid climate change may have jump-started human evolution two million years ago in this video from NOVA: "Becoming Human". CREDITS: https://www.pbslearningmedia.org/credits/clim10.sci.ess.watcyc.evoclimate/ LICENSE
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

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

Not every triangle is a right-angle triangle, so we can't always use Pythagoras and SOHCAHTOA to find missing sides and missing angles. We instead use the sine rule or the cosine rule. They can both be used to find either missing sides or missing angles in any triangle (right angle or not). Click h
Mesomerism simply explained - definition, rules & examples benzene & aniline - organic chemistry. Mesomerism is also called resonance, it describes the bonds in molecules with the help of several structural formulas. The possible structural formulas are the resonance structures. The more resonance s
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
The Pareto Principle, also known as the 80/20 rule, states that often 20% of causes produce about 80% of the results, while the remaining causes are responsible for the rest. Discovered by the Italian economist Vilfredo Pareto, the principle became a valuable rule of thumb that helps our minds under
