The effect this has had on human psychology, hunting practices, territoriality and social behaviour have been profound. Human evolution is the lengthy process of change by which people originated from apelike ancestors.

Oct 23, 2017· The study of the evolution of the human species can provide insight to understanding the violence, aggression and fear around us today. Humans have evolved as social, empathetic, collaborating and altruistic beings in small groups sharing common identities.
The evolution of human nutrition
the biology of food. Scientific and public interest in food covers many different perspectives, but since there is no discipline of food, food research tends to be carried out separately in such areas as ecology, physiology, and the neurosciences. The integration promised by Current Biology's multiple reviews is therefore particularly valuable.
Processing food before eating likely played key role in ...
Mar 09, 2016· Processing food before eating likely played key role in human evolution, study finds. They also found that by simply slicing meat with the sorts of simple tools available more than 2 million years ago, humans were able to swallow smaller, more easily digestible pieces than would have been possible without using tools.
With Gene Therapy We Could Direct Our Own Evolution The Crux
Mar 09, 2015· With Gene Therapy We Could Direct Our Own Evolution. Over millennia, constant infections would come to mean that 8 percent of the entire human genome is made up of inserted virus code. All this gene recoding of our bodies occurred under Darwin's rules, natural selection and random mutation. But nonrandom, deliberate human genetic engineering is new, and it is a big deal.
Viruses revealed to be a major driver of human evolution
Jul 13, 2016· The constant battle between pathogens and their hosts has long been recognized as a key driver of evolution, but until now scientists have not had the tools to look at these patterns globally ...
How technology and automation will impact human evolution
How technology and automation will impact human evolution. From robots and chatbots to virtual/augmented reality, machine learning, artificial intelligence (AI) and beyond, the physical space is littered with digital influence. The impact of increased automation is already upon us and influencing our lives in all possible ways.

Feb 25, 2013· Tracing the evolution of the human diet from our earliest ancestors can lead to a better understanding of human adaptation in the past. It may also offer clues to the origin of many health problems we currently face, such as obesity and chronic disease.
How Climate Change May Have Shaped Human Evolution ...
Sep 30, 2014· Evidence is building that past climate change may have forged some of the defining traits of humanity. These periods of oscillation happened very rapidly on geologic time scales. Intriguingly, the most pronounced fluctuations happened 3 to million years ago, and again a million years later—during the two major periods of early human advancement.
How are humans affecting the evolution of other species ...
Mar 08, 2016· Well, humans are the biggest changers of the environment around. All those changes are going to affect the "evolution process" of the species in those ecosystems. Many times that effect is the extinction of species. We are in the middle of a huge, humancaused extinction event.
Past, present, future: how human evolution and climate are ...
Jun 06, 2016· A new age. The only natural parallel with the speed of climate changes over the last few decades is during mass extinctions, when the pace of change exceeds the ability of species to adapt. Mass extinctions in the past have been triggered by largescale volcanic events or asteroid impacts. This time it's us causing the changes.
HOW CULTURE DROVE HUMAN EVOLUTION |
Typically, people thinking about human evolution have approached this as a twopart puzzle, as if there was a long period of genetic evolution until either 10,000 years ago or 40,000 years ago, depending on who you're reading, and then only after that did culture matter, and often little or no consideration given to a long period of interaction between genes and culture.
How CRISPR and Gene Editing Could Ruin Human Evolution | Time
Jan 09, 2017· In reality, Darwin showed us that evolution does not progress toward an ideal model or a more perfect form, but instead is a work of tinkering toward adaptation in .
How sliced meat drove human evolution | Science | AAAS
Mar 09, 2016· Human teeth simply can't break up the flesh into smaller pieces we can swallow. "It's almost like chewing gum," Zink says. Chimps' teeth are similarly bad at chewing meat.
How cooking made us human | Harvard Magazine
Evolution by Fire. That is because cooking—thanks to chemical processes that differ for starches, meats, and connective tissue—increases the number of calories in the food available to the human digestive system. Cooking also reduces the energy cost of digestion: gorillas, for example, must chew all day to absorb enough nutrition.
