paleontologist
常考释义
In 1972 paleontologist Stephen Jay Gould and Niles Eldredge challenged conventional wisdom with an opposing viewpoint, the punctuated equilibrium hypothesis, which posits that species give rise to new species in relatively sudden bursts, without a lengthy transition period.
在1972年，古生物学者Stephen Jay Gould和 Niles Eldredge用相反的论点挑战了世俗的结论，即断点平衡说，它假设了物种演变为新的物种是通过相对突然的爆发，并非通过长时间的过渡时期。

Even the tracks alone say a lot about the feeding behavior of the ancient birds, commented paleontologist Martin Lockley of the University of Colorado in Denver.
丹佛科罗拉多大学的古生物学家马丁•劳克雷评论说，即使只有这些足迹也很能说明这些古代鸟类的进食行为。
Now another interesting series of studies involve the skeletal remains of hunter-gatherers as compared with their agricultural relatives. And one such study from Greece and Turkey ... it indicates that the average height of hunter-gatherers at the end of
现在，有另一系列有趣的研究涉及到对比狩猎采集者和种植者的遗骸。有一个希腊和土耳其的研究表明，在冰河世纪末期，狩猎采集者的平均身高是…让我看看我的笔记…是的，男性的平均身高是5. 9英尺，女性的平均身高是5.5英尺。他们的骨头强壮，健康，体格健壮。但是，在农业革命后，遗骸显示人们的平均身高已经惊人地减少到男性5.3英尺和女性5英尺。骨骼样本的证据表明，他们患有营养不良引起的疾病，如贫血。这个结果非常有趣。马萨诸塞大学古生物学家进一步的研究表明，狩猎采集者的预期寿命为26年，但是早期农业社会人们的预期寿命不到

断点平衡论试着去解释化石记录的一个古怪的特点----在超过一个世纪的时间里它已经为古生物学者所熟悉，但一直被忽视。
来源于：阅读OFFICIAL30 P2Paleontologists would like to be much more specific about a dinosaur’s diet than simply differentiating carnivore from herbivore.
古生物学家不只是想要区分恐龙是食草还是吃肉，他们还想知道恐龙的具体饮食。
来源于：阅读OFFICIAL48 P2Some paleontologists have argued that these represent stream accumulations rather than final meals.
一些古生物学家认为，这些食物是积累下来的食物而不是最后一餐。

美国古生物学家David Raup和John Sepkoski曾经从大量化石群中研究物种灭绝的比率。他们指出，自从白垩纪时期中期以来，灭绝的物种不断增多，大约每隔两千六百万年就会定期发生一次。
来源于：阅读OFFICIAL15 P2Paleontologists have argued for a long time that the demise of the dinosaurs was caused by climatic alterations associated with slow changes in the positions of continents and seas resulting from plate tectonics.

来源于：阅读OFFICIAL5 P3This 700-million-year-old formation gives few clues to the origins of modern animals, however, because paleontologists believe it represents an evolutionary experiment that failed.
这些7亿年前形成的地层为现代动物的起源提供了一些新的线索。因为古生物学家们认为它代表着一次失败的进化试验，
来源于：阅读OFFICIAL5 P3At one time, the animals present in these fossil beds were assigned to various modern animal groups, but most paleontologists now agree that all Tommotian fossils represent unique body forms that arose in the early Cambrian period and disappeared before the end of the period, leaving no descendants in modern animal groups.
在一段时间内，人们认为这些化石中的动物分化出了各种各样的现代动物。但是古生物学家们现在却认为，所有的Tommotian化石都仅代表在寒武纪初期出现但到寒武纪结束时就消失了的特别生物。所以它们没有在现在动物中留下后代。
