These olfactory ratios were then plotted onto evolutionary trees that other researchers had earlier derived for bird evolution.
此嗅觉比率然后被绘制成进化树。进化是其它研究人员早其研究鸟类进化所做的一种图表。
Our relationship with trees goes back to our evolutionary roots-way back to when our ancestors thrived in the green canopy above.
人类与树的关系可以追溯到我们进化的源头去——那时候我们的祖先还生活在绿树形成的天棚上。
