Two clonal populations of vesicular stomatitis virus of approximately equal relative fitness were mixed together and allowed to compete during many transfers in vitro as large virus populations. Eventually, one or the other population suddenly excluded its competitor population, yet both the winners and losers exhibited absolute gains in fitness. Our results agree with the predictions of two major theories of classical population biology; the Competitive Exclusion Principle and the Red Queen's Hypothesis, where (in Lewis Carroll's words) "it takes all the running you can do to keep in the same place."
将两个相对适应性大致相等的水疱性口炎病毒克隆群体混合在一起,并在体外多次传代过程中作为大量病毒群体进行竞争。最终,其中一个群体突然排除了其竞争群体,但赢家和输家在适应性方面都表现出了绝对的提升。我们的结果与经典群体生物学的两个主要理论的预测一致;竞争排斥原理和红皇后假说,用(刘易斯·卡罗尔的话来说)“你得拼命奔跑才能留在原地”。
