Check the website here: http://enlites.com/ Dr. Andrew Berry is a lecturer in Organismic and Evolutionary Biology. He is an evolutionary biologist with a particular interest in Alfred Russel Wallace. His research combined field and laboratory methods to detect positive Darwinian selection (i.e. adaptive evolution) at the molecular level in natural populations. He has published two books: Infinite tropics: an Alfred Russel Wallace Anthology, with a foreword written by Stephen Jay Gould, and DNA: The Secret of Life with James Watson. This is the second part of our 2-part episode on the history of evolutionary theory/biology. In this episode, we start with population genetics, its early developments, how it led to the development of inclusive fitness theory, and what happened after the discovery of the double-helix structure of the DNA, what we learn about evolution by natural selection by understanding genetics, and how to detect adaptive evolution on the level of the genome. We then discuss speciation, what we know about it, and some of the controversies there. We address specifically the question of why there are more species more densely packed as one moves from the poles to the Equator. Finally, we talk about what we can learn by studying evolution in islands. -- A HUGE THANK YOU TO MY PATRONS/SUPPORTERS: KARIN LIETZCKE, ANN BLANCHETTE, PER HELGE LARSEN, LAU GUERREIRO, JERRY MULLER, HANS FREDRIK SUNDE, BERNARDO SEIXAS, HERBERT GINTIS, RUTGER VOS, RICARDO VLADIMIRO, CRAIG HEALY, OLAF ALEX, PHILIP KURIAN, JONATHAN VISSER, JAKOB KLINKBY, ADAM KESSEL, MATTHEW WHITINGBIRD, ARNAUD WOLFF, TIM HOLLOSY, HENRIK AHLENIUS, JOHN CONNORS, PAULINA BARREN, FILIP FORS CONNOLLY, DAN DEMETRIOU, ROBERT WINDHAGER, RUI INACIO, ARTHUR KOH, ZOOP, MARCO NEVES, COLIN HOLBROOK, SUSAN PINKER, THOMAS TRUMBLE, PABLO SANTURBANO, SIMON COLUMBUS, PHIL KAVANAGH, JORGE ESPINHA, CORY CLARK, MARK BLYTH, ROBERTO INGUANZO, MIKKEL STORMYR, ERIC NEURMANN, SAMUEL ANDREEFF, FRANCIS FORDE, TIAGO NUNES, BERNARD HUGUENEY, ALEXANDER DANNBAUER, OMARI HICKSON, FERGAL CUSSEN, YEVHEN BODRENKO, HAL HERZOG, NUNO MACHADO, DON ROSS, JONATHAN LEIBRANT, JOÃO LINHARES, OZLEM BULUT, NATHAN NGUYEN, STANTON T, SAMUEL CORREA, ERIK HAINES, MARK SMITH, J.W., JOÃO EIRA, TOM HUMMEL, SARDUS FRANCE, DAVID SLOAN WILSON, YACILA DEZA-ARAUJO, IDAN SOLON, ROMAIN ROCH, DMITRY GRIGORYEV, TOM ROTH, DIEGO LONDOÑO CORREA, YANICK PUNTER, ADANER USMANI, CHARLOTTE BLEASE, NICOLE BARBARO, ADAM HUNT, PAWEL OSTASZEWSKI, AL ORTIZ, NELLEKE BAK, KATHRINE AND PATRICK TOBIN, GUY MADISON, GARY G HELLMANN, SAIMA AFZAL, ADRIAN JAEGGI, NICK GOLDEN, PAULO TOLENTINO, JOÃO BARBOSA, JULIAN PRICE, EDWARD HALL, AND HEDIN BRØNNER!
