- Evolution Can Happen Without Natural Selection
- Natural Selection Is Still Happening in Humans
- Evolution Can't Be Stopped
Evolution is often used interchangeable with the phrases 'survival of the fittest' or 'natural selection'. Actually, these are not quite the same thing. 'Evolution' simply means the gradual change of a population over time. 'Natural selection' is a mechanism by which evolution can occur. Our Stone Age ancestors who were faster runners avoided being...
That makes sense for Stone Age humans, but what about nowadays? We don't need to outrun mammoths, we have medicines for when we're sick and we can go to the shops to get food. Natural selection needs a 'selection pressure' (e.g. dangerous trampling mammoths), so if we don't have these anymore, does this mean we stop evolving? Even with no selection...
As much as we have made things easier for ourselves, there are still selection pressures around us, which mean that natural selection is still happening. Like all mammals, humans lose the ability to digest milk when they stop breastfeeding. This is because we stop making an enzyme called lactase. In some countries, the population has acquired 'lact...
So, evolution can happen by different mechanisms like natural selection and genetic drift. As our environment is always changing, natural selection is always happening. And even if our environment was 'just right' for us, we would evolve anyway! Dr Alywyn Scally, an expert in evolution and genetics from the University of Cambridge, explains: "As lo...

Will Earth be uninhabitable in 2100?
Jun 25, 2021 · Again, the short answer is, “Of course not.” If Earth is uninhabitable in 2100, it will not be because our climate cannot support human life. As always, my longer answer requires context. The two different questions arise from the same place. In 2018, the IPCC released Global Warming of 1.5 ° C: An IPCC Special Report.
Jul 1, 2015 · The U.S. Army’s Human Terrain System (HTS), a program that embedded social scientists with deployed units, endured a rough start as it began deploying teams to Iraq and Afghanistan in 2007. 1 These early experiences had a lasting impact on the program. Although critics have written extensively about HTS struggles with internal mismanagement ...
Aug 15, 2014 · Human terrain is a complicated term. It has been plagued with controversy in recent years stemming from US Army implementations in the Middle East. This paper reviews the history of human terrain in three forms: as a human behavioral concept, a conflict based application, and a multidisciplinary area of research.
