Population a group of interbreeding organisms of the same species ( or other groups within which individuals may exchange genetic information ) occupying a particular space 种群：指占据特定空间的、具有潜在杂交能力的同一种植物的个体群（或者与其它个体群的个体进行基因交流） 。
We have come to understand now that due to human scientific interbreeding of our two species how we became intertwined consciousness when at another time this was not so 我们现在开始理解，我们是如何因人类对我们两个物种科学杂交繁殖而成为意识混杂的，而在另外时期却并不如此。
Isolating mechanism structural , physiological , behavioral , genetic , geographical , or other factors that restrict the interbreeding of one population with another , hence restricting gene flow 隔离机制：由于结构、生理、行为、遗传、地理或其它因素限制了一个种群与另一种群杂交的机制，从而限制了基因的流动。
Far extraterrestrials really come into earth and interfering with human affairs , or even interbreeding with us . examine the most compelling evidence of ufo visitations , with believers and skeptics alike 远太空的外星人确实进入地球，扰乱人类的生活，或者甚至与人类繁殖。通过检查这些最引人注目的ufo来过的证据和迹象，仍然有些人相信，而有人怀疑。
" i agree that the evidence still largely supports an influx of modern humans into europe , followed by the replacement of the neanderthals with , at most , a trivial amount of gene flow [ interbreeding ] between the populations , " he said 他说： “我同意证据仍然主要支持现代人进入了欧洲，最多（的可能）是尼安得达人被随之而来的人种间通婚的微量基因流替换了。 ”
（ a species may be defined as a group of organisms of interbreeding natural populations that are reproductively isolated from other groups and that share in common gene pools 物种是生物界发展的连续性与间断性统一的基本间断形式；在有性生物物种呈现为统一的繁殖群体，由占有一定空间，具有实际或潜在繁殖能力的种群所组成，而且与其他这样的群体在生殖上是隔离的。
But in addition to confirming previous findings , the nontaster form helps to answer one of modern anthropology ' s most controversial questions : as our homo sapiens ancestors spread across the world , did they interbreed with the more archaic hominids they met in europe and asia 这个苦味基因的突变除了可验证过去的发现外，还解开了现代人类学中最具争议的问题：现代智人的祖先扩散到世界时，是否和他们在欧洲和亚洲遇到的其他古代人猿类繁衍后代？
