Companies are on the verge of selling lab-grown meat. The new products are touted as environmentally friendly, but is it what consumers want and where exactly are the lines when it comes to genetic engineering?

When a strawberry from Chile and a strawberry from the United States met in a genteel French garden 200 years ago — on a blind date arranged by gardeners who wanted to create a better berry — it was love at first sight.

Previously, imported species from the US state of Virginia hadn't produced much, while the fruits of European varieties were very small. As it turned out, the Chilean genes held the magic ingredient, and nearly every strawberry you buy in the market today comes from that strain.

Luscious strawberries may be among the the tastiest results of genetic tinkering, but they are not the only. Mesopotamians started propagating wild grasses with the biggest seeds 10,000 years ago, which eventually turned them into the crops we now call rice, wheat, barley, oats, millet and rye.
