Mechanisms of Evolution
Gene flow, also known as gene migration, is the transfer of genetic material between populations. It occurs when individuals from different populations interbreed, introducing new alleles into a population. This process helps maintain genetic diversity and can counteract the effects of genetic drift and natural selection. For instance, if individuals from one population of plants migrate to a neighbouring population, they may introduce new genetic variations that could enhance the adaptability of the local population.

Our website is dedicated towards making knowledge and information about evolution accessible to all in an easy-to-understand way. We are committed to educating the common man about this very important part of science, and believe it shouldn't cost a single cent to learn and gain more knowledge.
WE PLAN ON STARTING A BLOG AS PART OF OUR WEBSITE. WE WILL CONSTANTLY BE UPDATING IT WITH NEWS, NEW DISCOVERIES, VIDEO CLIPS, OUR OPINIONS ON THINGS, PHOTOS, AND ALL THINGS EVOLUTION-RELATED! IT'LL ALSO INCLUDE A SECTION FOR USERS TO ENGAGE AND HAVE DISCUSSIONS WITH EACH OTHER, AND WE PLAN ON MAKING IT THE GO-TO PLACE FOR ANYONE AND EVERYONE INTERESTED IN EVOLUTION! SO STAY TUNED FOR EXCITING STORIES Stay Tuned
