But if you remember the four legged creature like Boston Dynamics robots and you've picture 10 of them marching in unison while dragging something heavy, like some robotic sled dog army, then maybe you did have this in mind.

但是如果你还记得像波士顿动力学机器人这样的四腿生物，你会想到它10个沉重的东西的同时齐齐行进，就像机器雪橇狗大军一样，那么也许你确实有这个想法。

And so a single scuba diver can go anywhere from the surface to 40 meters or 120 feet deep to measure the hydrodynamic signatures that organisms create.

因此，一名水肺水员可以至水面以下40米（约120英尺）的深度，去测量生物体所产生的流体动力学特征。

The finding should lead to new strategies to fight drug resistance. And it could also improve our take on evolutionary dynamics, in systems that apparently experience selection pressure at both the individual and group levels.

此项发现可以研究新的策略来对付抗药性。此外，它还完善了进化动力学，以及物竞天择压力下的个体与群体的生物系统。

And so terrestrial organisms, like my cute dog Kieran, might be leaving footprints behind in dirt or in sand, but marine organisms leave footprints in the form of what we call wake structures, or hydrodynamic signatures, in fluid.

因此，陆地生物，比如那可爱的狗狗基兰，可能会泥土或沙地上留下足迹，而海洋生物则会流体中留下称之为尾流结构或流体动力学特征的“足迹”。

Some of the world's leading figures in paleontology, biomechanics, aerodynamics and scientific reconstruction have come together for a rare collaboration.

古生物学、生物力学、空气动力学和科学重建领域的一些世界顶尖人物齐聚一堂，进行罕见的合作。
