(A) The de novo inactivation model requires many rounds of inactivation and reactivation: the paternal germline initiates meiotic sex-chromosome inactivation, but the X chromosome is completely ...

现在看看自己拿着手机的手，想不想感叹一句这五根手指简直是天生玩手机圣体，要是长成鱼鳍、马蹄，可怎么刷手机啊！手指不是五根也很酷啦~人和灵长目的手指脚趾都呈现五根，各种耗子、豺狼虎豹也是前肢五根手指，鳄鱼和一些蜥蜴也都是，那你有没有想过，为什么要五根手 ...

“We couldn’t use transcriptomics to identify which subset it was, because the ontogeny markers were diluted,” says Merad. To solve this problem, she added CITE-seq to the scRNA-seq analysi ...

The study uncovers gene expression signatures that predict neonatal sepsis, highlighting the potential for early intervention ...

Specifically, Haeckel proposed that "ontogeny recapitulates phylogeny." This pithy bit of jargon, when translated into English, asserts that as an embryo develops, it passes through stages that ...

Here we demonstrate an unexpected degree of flexibility and cognition in a decision made by a hunting animal at reflex-like speed. Based on observing initial speed, direction, and height of falling ...

Social Cognition in a Usage-Based Model of Language Change – from Immediate (I-I) to Extended Intersubjectification (E-I) 4. The Intersubjective Gradience Model Applied – from Immediate (I-I) to ...

One of Darwin's contemporaries, German biologist Ernst Haeckel, summed up the argument in a famous, pithy statement: "Ontogeny recapitulates phylogeny.'' That is to say, in the process of ...

The gray squirrel’s appearance differs seasonally. The yellowish brown summer coat becomes thicker and gray in winter, the pelage of some individuals strikingly silver-gray. Underparts and eye-rings ...

In each successive annual non-breeding plumage, satellites only grow more and more prominent white neck rings. The ontogeny of this plumage character is similar to that of "status signalling badges" ...

Early childhood vitamin D insufficiency affects neuronal development, axonal connections, dopamine ontogeny, and brain structure and function. The review findings highlighted fatigue modulation by ...
