Answer:
Approximately 8,000 years ago, changes in <u>wheat </u>occurred as humans chose plants that did not <u>shatter </u>and therefore held seeds on the plant making it easier to harvest the grain.

8000 years ago when wheat mature, some varieties shatter and maturity while others keep their wheat spikes intact. Shattering in wheat is an undesirable process in agriculture as it makes harvesting more difficult. Over the millenia, humans decided to plant only wheat that hold their seeds at maturity and do not shatter as this make it easier to harvest the grain. This led to a reduction in the number of wheat varieties that shatter.

Greek and Roman are bedrock of the classical culture of Western civilization.
From Greece we inherited a political system and governing model called democracy which flourished in Athens many centuries before our era. The great Greek philosophers Socrates, Plato and Aristotle left us their thinking and philosophy that are the first major works on society and politics, ethics, morality, government. Greek mythology, adopted by the Romans, provided stories and enduring symbols in Western cultures, as well as magnificent inspiration for some of the best Western art and literature. Greek comedy and tragedy are the first major heights of world theater, and Homer gave us the Iliad and the Odyssey. Greek and Roman architecture still serve as models for many of our modern buildings. Thanks to Herodotus, the first world historian, we know about the Medic Wars and the conquests of Alexander the Great.
Rome inherited us also great thinkers, writers, speakers, the art of oratory. From Roman governing system, we have inherited an institution that still exists today in modern democracies: the Senate. Latin , the Roman people´s language, was adopted as the official language of the Catholic Church and of scholars for many centuries; it is the mother of contemporary Romanic languages such as French, Italian and Spanish.
