  The Greatest Show on Earth: The Evidence for Evolution(部分)

  We investigated the possible role of variation in predation pressure in the phenotypic divergence of two island populations of the Italian wall lizard, Podarcis sicula. In 1971,ten adult specimens from the island of Pod Kopi ˇste (Adriatic Sea, Croatia)were transported to the island of Pod Mrcˇaru, 3.5 km east, where they founded a new population. Although the two islands resemble each other in general physiognomy (size, elevation, microclimate) and in the absence of terrestrial predators, lizards from the newly established population are now on average larger and have shorter hind limbs. They also exhibit lower maximal sprint speed as measured on a racetrack, and fatigue faster when chased in a torus track. In the field, lizards from the original population of Pod Kopiˇste respond to a simulated predatory attack by fleeing at larger approach distance sand by running further from the predator than lizards from Pod Mrc ˇ aru. These changes in morphology, behavior and performance may result from the relaxed predation intensity on the latter island.

  文章大意:自然科学类。本文话题有关动物进化,讲述了克罗地亚在地中海上两个岛屿的蜥蜴进化关系。根据一种蜥蜴的迁徙,科学家推测两地的动物基因上一样,但这样的推测是不太成立的,因为进化一直在进行中。文章第二段从形体和猎物两方面讨论了两岛蜥蜴的区别,一个偏向食草,体型更大更长,一个吃昆虫。第三段涉及了食草对咬合肌的大小影响。
