Neanderthals 'R' Us

        Thousands of years ago we weren't the only humans on Earth, there were different species of humans. One of those species were the neanderthals. They lived among humans but for some reason they went extinct and we survived. Through time researched has showed that at one point neanderthals had sex with humans like us. That means that although neanderthals may be extinct from Earth they still live in us. Most people have neanderthal genes in their DNA.
