还记得靠舞技风靡网络的葵花凤头鹦鹉雪球吗?现在,又有一种新的动物加入了跟上节拍的行列。认识一下罗南,这只加州海狮会随着《Boogie Wonderland》和其他曲子的节拍摇晃脑袋(见下方视频)。除了人类,很少有物种表现出节奏感,而最令人信服的例子都是鹦鹉及其亲属——这些动物都具有出色的声音模仿能力。因此,科学家们推测,保持节拍与复杂的发声学习能力有关。但是罗南挑战了这一观点,因为海狮不是声音模仿者。加州大学圣克鲁兹分校的研究生彼得·库克和他的同事训练罗南在简单的节奏轨道上点头,一旦她掌握了这项技能,她就能够跟上不同节奏的新歌。“人类的音乐能力可能实际上与动物具有共同的基础,”库克说。“人们一直认为动物缺乏这些能力。在某些情况下,人们只是没有观察。”一篇详细介绍罗南能力的报告本周将在《比较心理学杂志》上发表。

She is fascinated by human origins, which she has covered for more than 25 years. Recently she has become obsessed with birds. Her reporting has taken her to caves in France and Croatia that Neandertals once called home, to the shores of Kenya's Lake Turkana in search of the oldest stone tools in the world, to Madagascar on an expedition to unearth ancient mammals and dinosaurs, to the icy waters of Antarctica, where humpback whales feast on krill, and on a "Big Day" race around the state of Connecticut to find as many bird species as possible in 24 hours. Kate is co-author, with Donald Johanson, of Lucy's Legacy: The Quest for Human Origins. She holds a bachelor of science degree in biological anthropology and zoology from the University of Michigan.
