Human evolution is still happening - possibly faster than ever
Modern medicine's ability to keep us alive makes it tempting to think human evolution may have stopped. Better healthcare disrupts a key driving force of evolution by keeping some people alive longer, making them more likely to pass on their genes.

Human Evolution

Evolution is a gradual change in the DNA of a species over many centuries, occurring by natural selection when traits created by genetic mutations promote survival or reproduction in an organism.


Stretch Genes

  • Human beings adapt to their environments genetically, over a period of time. 
  • Developing countries having populations with no access to proper health care continue to survive and...


Our Diet

What we consume or don't consume influences our genes. Example: Countries where milk isn’t taken commonly, develop lactose intolerance and other digestive problems.



Biased Gene Conversion

Certain molecular repairs seem to be happening in a biased way in our bodies, according to recent scientific studies of the genome. Certain ‘fast-evolving’ genes are rapidly accelerating, causing a...



Processed Food in History

The need for food preservation has historically led the Ancient humans to develop techniques to process food.

From learning to control fire to grinding grains, our ancestors have been able to...

Evolution: Shaping Up Humans

Processed food has aided the evolution of Homo Sapiens: As food became easy to eat and digest, our jaws and teeth became less powerful and smaller.

The shape of our brains and even the development of language resulted partially from our eating habits in our evolutionary path.

Changes in DNA

Processed food has changed our DNA and the way we look. 

The current crop of super processed foods is altering our insulin resistance, teeth, metabolism, brain chemistry, and internal organs.

We remain vulnerable

For all our advances in medicine, we remain more vulnerable to pandemics than we would like to believe.

To understand our vulnerability and to establish what steps we need to take to end ...

The Black Death

In 1347, the Black Death came to Europe, first brought by the Mongol army, then spreading through Europe.

In six years, tens of millions fell gravely ill. Nearly half of all Europeans succumb to the Black Death, one-third of Egyptians and Syrians were killed, and it also laid waste to parts of central Asia, India, and China.

Disasters that scarred humanity

  • In AD 541, the plague of Justinian struck the Byzantine empire, killing roughly 3% of the world's population.
  • When Europeans reached the Americas in 1492, the two populations exposed each other to completely novel diseases such as measles, influenza, and smallpox.
  • Centuries later, the interconnected world made a global pandemic possible. The Spanish flu of 1918 spread to six continents where between 3% and 6% were killed.

However, even the Spanish flu pandemic had a minimal apparent effect on the world's development. It was less significant than the first world war, which had a smaller death toll but a more substantial impact on the course of history.

Survival of The Fittest

The famous Charles Darwin theory, 'survival of the fittest' has turned into a cultural cliché. The theory proposes that living beings naturally fight and compete with each other to survive.


Collaborative Interdependence

Hundreds of studies on plants and animal behavior in recent years reveal that living things, including humans, are in reality multispecies events of collaboration and interdependence.

This is seen in the way fungus helps nurture and connect trees, or the way algae and coral form a partnership to create colorful coral reefs.

Life is more complex and collaborative than previously thought.

The Climate Crisis

The recent findings which prove that competition is not natural, at least not more than collaboration, pave the way to think about our relationship with the planet, and the millions of species inhabiting it.

Environmentalists are tackling the climate crisis assume that people are by nature bound to harm ecology, and will consume and plunder the natural resources. This leaves them with a narrow set of solutions to control the crisis.
