DNA studies, for example, suggest that our ancient human ancestors interbred, with Neanderthals possibly being absorbed into our gene pool and disappearing as their own distinct hominid species.
例如，DNA研究就显示古代人类的祖先也曾进行杂交，尼安德特人的基因很可能已被我们的基因库所吸收，而他们做为不同的原始人类物种却已经消失。
Recent DNA studies have indicated that the neandertal was an entirely different species and did not merge into the H. sapiens sapiens gene pool.
最近的基因研究已经表明，穴居人是一个完全不同的物种，并没有合并到智人智人基因库。
