【昨日复习】
In physics, one approach takes this impulse for unification to its extreme, and seeks a theory of everything—a single generative equation for all we see.

【今日长难句】
Here, Darwinism seems to offer justification, for if all humans share common origins, it seems reasonable to suppose that cultural diversity could also be traced to more constrained beginnings.
【结构解析】
1. 句子主干为：Darwinism/ seems/ to offer justification，译为：达尔文主义似乎给出了一个正当理由。
2. for 为连词(conj.)，可译为 “因为”。if all humans share common origins 为条件状语从句，it seems reasonable to suppose … 中“it”为形式主语，to suppose that …为真正的主语；
3. “that cultural diversity coula also be traced to more constrained beginings”为“suppose”的宾语从句，cultural diversity 译为：文化多样性；be traced to 意为：追溯到…；more 修饰constrained; constrained 修饰beginnings; more constrained beginnings 译为：更有限的开端。

【明日预告】
To filter out what is unique from what is shared might enable us to understand how complex cultural behavior arose and what guides it in evolutionary or cognitive terms.
