Nearly all genetic variants that influence disease risk have human-specific origins; however, the systems they influence have ancient roots that often trace back to evolutionary events long before the origin of humans. Here, we review how advances in our
In this lesson, we will discuss what evolutionary relationships mean, how we describe them, and how we determine them using morphological and...
The Evolutionary Origin of Plants The evolutionary history of plants has been marked by a series of adaptations. The ancestors of plants were photosynthetic single-celled organisms probably similar to today’s algae. Like modern algae, the organisms that gave rise to plants presumably lacked true ...

以 ancient algae 做过渡点，找到原文倒数第二句，所以答案非 C 即 D。倒数第二句说有feature 使它们忍受和极端温度干旱，而待插入句讲这些都是什么样的特点，也刚好与后面的 these adaption 形成很顺的过渡，正确答案是 D。此外，待插入句中的 among other things 也是一个很好的点 ...
The Evolutionary Origin of Plants The evolutionary history of plants has been marked by a series of adaptations. 植物的“祖先”是能够进行光合作用的单细胞生物,或许和今天的藻类相似。 就像今天的藻类,进化出植物的组织可能缺少真正的根、茎、叶以及复杂生殖结构——例如花朵。" >The ancestors of plants ...
A.Darwin saw evolutionary change as happening slowly and gradually. B.Gaps in the fossil record were used to explain why it is difficult to see continuous small changes in the evolution of species. C.Darwin's evolutionary thesis was rejected because small changes could not be observed in the ...
