概括
人类和非人类灵长类动物 (NHP) 在听觉皮层中处理声音的时间尺度不同. 虽然两者都在短时间和长时间的窗口中使用类似的区域,但人类的初级听觉皮层对更长的时间表更敏感,可能用于语音处理.

01:54Convergent Evolution
31.3K
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

3.7K
John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.
