Eurasia's long east-west axis facilitated the spread of agriculture because it allowed for similar climate zones and day lengths, making it easier for crops and animals to adapt and spread. This led to the domestication of plants and animals more quickly across different regions.
Jared Diamond argues that areas with similar climates to the Fertile Crescent developed agriculture earlier because they contained a high number of wild plant and animal species suitable for domestication. This abundance of potential resources made it easier for societies to transition from hunting and gathering to agriculture as a means of food production.
According to Jared Diamond, the worst mistake in human history was the switch to farming.
