鱼状的动物

Whereas the proximal part of the tetrapod limb skeleton can easily be homologized with the paired fin skeletons of sarcopterygian (lobe-finned) fish, there has been much debate about the origin of digits.

早期的假设认为，四足动物的足趾与鱼类的放射鳍同源，但根据发育研究结果，同时根据一种名叫&潘氏鱼&、与陆地脊椎动物密切相关的目前已经灭绝的鱼（这种鱼似乎没有末梢的趾状放射鳍）的鳍，这一观点似乎并不可靠。

The newly found species, Tiktaalik roseae, has a skull, a neck, ribs and parts of limbs that are similar to four-legged animals known as tetrapods, as well as fish-like features such as a primitive jaw, fins and scales.

最近发现的种类， Tiktaalik roseae，有一块头骨、一个脖子、与四足动物tetrapods类似的肢体的部分肋骨，以及似鱼功能，例如一个原始下颌、飞翅和鳞状体。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
