Khan Academy is a non-profit educational organization created in 2006 by educator Salman Khan with the aim of providing a free, world-class education for anyone, anywhere. The organization produces short lectures in the form of YouTube videos. In addition to micro lectures, the organization's website features practice exercises and tools for educators. All resources are available for free to anyone around the world. The main language of the website is English, but the content is also available in other languages.
The founder of the organization, Salman Khan, was born in New Orleans, Louisiana, United States to immigrant parents from Bangladesh and India. After earning three degrees from the Massachusetts Institute of Technology (a BS in mathematics, a BS in electrical engineering and computer science, and an MEng in electrical engineering and computer science), he pursued an MBA from Harvard Business School.
In late 2004, Khan began tutoring his cousin Nadia who needed help with math using Yahoo!'s Doodle notepad.When other relatives and friends sought similar help, he decided that it would be more practical to distribute the tutorials on YouTube. The videos' popularity and the testimonials of appreciative students prompted Khan to quit his job in finance as a hedge fund analyst at Connective Capital Management in 2009, and focus on the tutorials (then released under the moniker "Khan Academy") full-time.
Anna Katherine "Kay" Behrensmeyer is an American taphonomist and paleoecologist. She is a pioneer in the study of the fossil records of terrestrial ecosystems and engages in geological and paleontological field research into the ecological context of human evolution in East Africa. She is Curator of Vertebrate Paleontology in the Department of Paleobiology at the Smithsonian Institution's National Museum of Natural History (NMNH). At the museum, she is co-director of the Evolution of Terrestrial Ecosystems program and an associate of the Human Origins Program.
Behrensmeyer received her B.A. from Washington University in St. Louis.
In 1968, Behrensmeyer made a detailed investigation of Lothagam, a Kenyan paleontological formation dating to the late Miocene-early Pliocene period. Within the succession, she identified six lithostratigraphic units. She later compiled a chart for the 400 fossil specimens collected in 1967 and published a faunal list for Lothagam 3 in 1976.

A popular myth is that radioactive dating methods confirm the geologic time-scale and the concept of human evolution. The methods appear so impressive that many Christians accept them as evidence that the earth is very old. Many have been taught that radiometric dating methods are absolute. But exactly how solid are those dates?

Today Paul Pepper welcomes CAROL WARD, Prof. of Anatomy at the University of Missouri, and NADEGE UWASE, Dir. of MU African Interdisciplinary Studies Hub. They invite everyone to a symposium titled "Our African Origins" tomorrow at the Bond Life Sciences Center on the MU campus! Keynote speaker, Dr. Meave Leakey, appears on stage tonight at the Missouri Theatre. Watch for details! March 21, 2016 The mystery of our origins fascinates us all. Who are we as a species? Where did we come from? Why do we look the way we do, act the way we act, think the way we think? The story of where humans came from starts in Africa. MU African Interdisciplinary Studies Hub invites you to join internationally recognized leading scholars who are recovering the fossil evidence of our origins in Africa and l...

Dating of very old specimens via two different radioisotopes and their decay.
Kent Hovind shows how Potassium Argon dating has many fatal flaws. {--Since many of my individual videos do not explain why evolution is imagination, I will post the links here: Evolution is scientifically IMPOSSIBLE -- the ultimate disproof: http://www.youtube.com/watch?v=iNdhAYVtaDM ; why there is no mechanism to make entirely new genetic information (thus, evolution would be impossible): http://www.youtube.com/watch?v=j_8v3UJB8Vg ; why the earth was created ex nihilo: http://www.youtube.com/watch?v=xUPFRRTfv58 ; and why radiometric dating is a fallacy: http://www.youtube.com/watch?v=YTrXa6WIn1o.--} Don't forget to add me as a friend if you are anti-evolution!
