Humans have been around for hundreds of millions of years, and during that time our species has undergone some pretty significant evolution. Speculation for human evolution has long been all over the place, largely because we are only able to guess what is next for us as a species. Thankfully, science has come far enough to allow us to speculate with a somewhat increased amount of certainty. This article will discuss what we can expect from future human evolution, as well as what defines evolution and if humans have a need to continue evolving.

Evolution is defined as the gradual change in the characteristics of a species over the course of generations. The human species has undergone enough changes over the course of time to claim the status of having been through several of its own stages of evolution.

Throughout these changes, our species has become taller, more dexterous, and less hairy, to name a few of our modernized traits. There have also been variations in the study of human evolution over the last few centuries. However, the 19 th century also welcomed the discovery of fossilized Neanderthal remains, which kicked off a gradual chain of more fossil discoveries throughout the 20 th and 21 st centuries.

With the world around us changing constantly, humans need to continue adapting more than ever.

It isn't obvious, but humans are still evolving. So what will the future hold?

There are plenty of things we could see when humans undergo the next stage of evolution—so many, in fact, that we were hard-pressed to pick only a certain number of possible evolutionary changes. There are many opposing belief systems on the topic of evolution, which made it even tougher to choose the most viable evolution possibilities.

If humans continue to have abundant access to adequate nutrition, there is no telling how tall we can grow in the next stages of evolution. Did you know that in the last , years, human teeth have decreased in size by nearly half?

The disappearance of wisdom teeth is already taking place in some ethnic groups, as they serve no purpose to humans today. Due to the lack of need to accommodate large teeth for larger prey and the advancements in the human diet, we can expect our teeth to get even smaller throughout the course of time. There are millions of people today who are born without little toes, which leaves scientists to wonder if the absence of the fifth toe is an early evolutionary trait in humans. Avoiding the usual narrative, from bipedal ape-like creature to complex behaviour, Lee offers an original journey along our singular evolutionary path.

When did our ancestors lose their fur? Did the taste for meat change our destiny? Was farming a blessing or a curse?

10 Ways Humans Are Likely To Evolve

Is altruism unique to us? Succinctly and engagingly, Lee revisits these and other key questions about the story of our evolving species — and gives some unconventional answers.

Notably, she supports multiregionalism. Thus, she counters the sometimes rigid interpretations of the fossil record propounded in a literature dominated by the English language and the Western scientific community. In her book, Asia makes a comeback as a birthplace of modern humans and their ancestors. She also discusses the Denisovans, the mysterious hominins that coexisted with modern humans and left behind extensive DNA, but few fossils.

Not everything in Close Encounters with Humankind is about the past. Are humans still evolving? Lee challenges this view and traces a cascade of other evidence for ongoing human evolution.

She points to studies on skin colour as evidence. Dark skin is thought to have evolved in the first furless hominins in Africa, to protect against the ultraviolet radiation in intense direct sunlight. Hominins living in higher latitudes, went this line of reasoning, would be exposed to less UV radiation, and so would need less-active melanocytes the cells that produce the pigment melanin. That might largely explain the lighter skin of populations in regions farther from the Equator.
