“How did this grass turn from insignificant to ubiquitous? Wheat did it by manipulating Homo sapiens to its advantage. This ape had been living a fairly comfortable life hunting and gathering until about 10,000 years ago, but then began to invest more and more effort in cultivating wheat. Within a couple of millennia, humans in many parts of the world were doing little from dawn to dusk other than taking care of wheat plants. It wasn’t easy. Wheat demanded a lot of them. Wheat didn’t like rocks and pebbles, so Sapiens broke their backs clearing fields. Wheat didn’t like sharing its space, water and nutrients with other plants, so men and women laboured long days weeding under the scorching sun. Wheat got sick, so Sapiens had to keep a watch out for worms and blight. Wheat was attacked by rabbits and locust swarms, so the farmers built fences and stood guard over the fields. Wheat was thirsty, so humans dug irrigation canals or lugged heavy buckets from the well to water it. Sapiens even collected animal faeces to nourish the ground in which wheat grew.”

“Survival in that era required superb mental abilities from everyone. When agriculture and industry came along people could increasingly rely on the skills of others for survival, and new ‘niches for imbeciles’ were opened up. You could survive and pass your unremarkable genes to the next generation by working as a water carrier or an assembly-line worker.”

“The self,” Blackmore writes, “is just a fleeting impression that arises with each experience and fades away again. . . . There is no inner self,” she argues, “only multiple parallel processes that give rise to a benign inner delusion—a useful fiction.” She argues that consciousness itself is a fiction.”

“tap out a single grain of salt from a shaker. You could line up about ten skin cells along one side of it. You could line up about a hundred bacteria. Compared to viruses, however, bacteria are giants. You could line up a thousand viruses alongside that same grain of salt.”
