The team showed that this change in bite was connected with the development of agriculture in the Neolithic period. Food became easier to chew at this point. The jawbone didn’t have to do as much work and so didn’t grow to be so large.

这是2022新高考全国卷1阅读理解第D篇中的一段。

我对其中的The team showed that…不是很理解。因为我见过“主语+show that…”这类句式的主语通常是“事物”。如：

The scan showed that she was expecting twins. 扫描显示她怀了双胞胎。

Medical tests showed that he was sterile. 医学检查表明他没有生育能力。

The inquiry showed that bribery was widespread. 调査显示贿赂乏风极为普遍。

The X-ray showed that her leg was not broken. X光片显示她的腿没有骨折。

The sonogram showed that the fetus was developing normally. 超声波扫描图显示胎儿发育正常。

The survey showed that Britain’s trees are in good health. 调查显示英国的树木状况良好。

The monitor showed that someone was moving around in the car park. 监视器显示有人在停车场走动。

Analysis showed that cocaine was present in the mixture. 分析的结果表明混合物中含有可卡因。

但这类句式好像没有见过是“人”作主语的（我把 team 看作是“人”）。所以来请教一下专家老师！
