Почему теория эволюции — это теория, а не гипотеза? Чем теории отличаются от гипотез? Как развивалась теория эволюции? Как она подтверждается и применяется? Почему теория эволюции Дарвина работает?

Все, что нужно знать об открытии, редактировании и функциях ДНК.
#биология #ДНК
В курсе рассказано о самых фундаментальных аспектах ДНК, особенно о тех, при изучении которых особую роль играют не только биология и генетика, но и химия, физика и математика: как была открыта структура ДНК и почему это открытие считается одним из крупнейших в истории науки; об асимметрии всего живого в отношении правого и левого; о центральной догме молекулярной биологии — универсальном законе живой материи; о том, почему ДНК бывают линейными у одних организмов и замкнутыми в кольцо у других; о мутациях, повреждениях текста ДНК, ведущих к многочисленным наследственным болезням; о возникающей на наших глазах революционной технологии редактирования ДНК, которая позволит в недалеком будущем исправлять ошибки в тексте ДНК больного.

ABOUT TEDx
In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
A chance encounter with members of the Ku Klux Klan led black musician Daryl Davis on a quest to determine the source of the hate. His unorthodox, yet simple approach, has wielded surprising results and just might be the solution for all racial discourse.
Daryl Davis graduated from Howard University with a degree in Jazz. As a pianist, vocalist, and guitarist, he performs nationally and internationally with The Daryl Davis Band. He has also worked with such notables as Chuck Berry, Elvis Presley’s Jordanaires, The Legendary Blues Band, and many others.
In 1983, A chance occurrence after one of his performances led him to befriend a member of the Ku Klux Klan. This eventually led Daryl to become the first black author to travel the country interviewing KKK leaders and members, all detailed in his book, Klan-Destine Relationships. Today, Daryl owns numerous Klan robes and hoods, given to him by active members who became his friends and renounced the organization.
Since his journey began, Davis has joined an all-white country band, attended KKK rallies, and accepted a “certificate of friendship” from the Traditionalist American Knights of the KKK. He’s even the godfather of former Klan Imperial Wizard Roger Kelly’s granddaughter.
Davis has received the Elliott-Black and MLK awards as well as numerous other local and national awards for his work in race relations, and is often sought by media outlets as a consultant on the KKK and race relations. He is also an actor with stage and screen credits, appearing in the critically acclaimed HBO police drama, The Wire, and most recently, as the subject of the documentary Accidental Courtesy, which filmed his real life encounters with Ku Klux Klan and neo-Nazi leaders as he helps to dismantle racism across the United States

-عندما تنصاع المدن لشروط الريف في هندستها الاجتماعية والجغرافية والاقتصادية ، وتصبح وسائل ومنظمات المجتمع المدني _ بدلاً عن كونها وسائل لخلق ولائات جديدة اكثر حداثة ومواكبة _ تصبح رافعات للولاء القبلي ومرسخة له ، كما تقف عائقاً أمامنا وتجعلنا نواجه الكثير…
— خالد محمد نور في حديث مليء بالشجاعة والقوة ، لمواجهة مجموعة من المفاهيم المجتمعية الخاطئة.
When cities comply with the conditions of the countryside in their social,engineering geographical, and economic, civil society means and organizations — rather than means of creating new and more modern and aligned loyalties — it may become upgraders for tribal loyalty and anchor it down.
