Last summer, while on vacation with my hubby, I swam a few laps in a pool. I absolutely loved it. I adore being in the water, and Iâd forgotten how all over nice a swim can feel â tiring in a good way and meditative. Plus, thereâs the bonus that itâs not hard on my still-a-little-bit-recovering right knee. After that trip, I told myself Iâd go home and pick up lap swimming.
Evolution of Maize Agriculture Corn or maize (zea mays) is a domesticated plant of the Americas. Along with many other indigenous plants like beans, squash, melons, tobacco, and roots such as Jerusalem artichoke, European colonists in America quickly adopted maize agriculture from Native Americans.
Scientists confirm early humans were from Africa but their route out was via Arabia not Egypt. Our human ancestors did come from Africa but left the continent to spread across the world via a different route than first thought, scientists have revealed. A six-year study mapping genetic patterns found that people who ended up in Europe, Asia and Oceania got there by crossing the sea to Arabia around 70,000 years ago. Scientists had thought that humankind left for other continents in a northern direction through Egypt's Sinai region but now it seems they wandered further south, probably via Yemen.
