They’ve undergone a transformation from selective breeding that has tailored them to suit our picky tastes and conveniences. More recently, fruit and veg have been molded by genetic engineering, allowing us to pick ‘n’ mix the best genes from desirable plants.

And, for centuries, it remained the lingua franca in the Ancient Near East.

The Evolution Of Man's Face Over The Course Of 6 Million Years. No Link Between Introduction of Agriculture & Human Population Growth. Currently, the human population growth is about 1% per year.
Prehistoric human population growth, from beginning of the end of the Ice Age was just 0.04% annually until about 200 years ago, when a number of factors led to higher growth rates, such as modern medicine. We have been taught that the agricultural revolution increased population growth to some extent… Until now. Prehistoric human populations of hunter-gatherers in a region of North America, between modern day Colorado and Wyoming, grew at the same rate as farming societies in Europe, according to a new radiocarbon analysis.
The study used charcoal hearths as a symbolism of human activity. For humans in the region that is now Wyoming and Colorado between 6,000 and 13,000 years ago… People who foraged on animals and plants to survive; the analysis showed a long-term annual growth rate of 0.041 percent, consistent with growth that took place throughout North America.
