向太空移民是人类的梦想,但太空飞行危险重重,谁能够充当探路者呢?英国科学家最近确认,线虫是个可行的选择。他们分析说,用线虫担任太空探路者有三大优势:首先,线虫与人类有可比性。线虫虽然在外形上与人类相差巨大,但基本生理活动与人类非常相似。它们在地球上就被长期用作科学研究中的模式生物。其次,线虫能够在太空繁衍,因此种群可以经历漫长的太空旅行。第三,人类已经拥有 Immigrants to space is a human dream, but space flight dangerous, who can act as a pathfinder? British scientists recently confirmed that nematodes is a viable option. They analyzed that using nematodes as space pathfinder has three major advantages: First, nematodes are comparable to humans. Although the nematode in appearance and human difference is huge, but the basic physical activity is very similar with humans. They have long been used on Earth as model organisms in scientific research. Second, nematodes can multiply in space, so the population can experience long space travel. Third, humans already have
