瑜伽師地論略纂 15.156

15.156

論云「或有人或人相」者，解云：謂羯剌藍等位，即隨胎上，名重殺生。此大乘亦犯波羅夷。諸部小乘，除薩婆多，餘皆不成波羅夷，以未人相故。又解：人相，謂非人變為人，意欲殺人故殺，此名重。「僧祇」者，僧伽言眾，今言僧祇，即名眾物，聲轉如此。

Regarding the treatise's statement, "either a human or having human characteristics": this is explained as referring to stages such as the kalala; that is, as soon as it enters the womb, it is called grave killing. In the Mahāyāna, this also incurs a pārājika. Among the various Hīnayāna schools, except for the Sarvāstivāda, in all the rest it does not constitute a pārājika, because it does not yet have human characteristics. Another explanation: 'human characteristics' means a non-human transforming into a human; if one kills with the intention to kill a human, this is called grave. As for "saṃghika": saṃgha means community (gaṇa); now saying saṃghika means communal property; the phonetic change is like this.
