Could there be new human species that have emerged since Sapiens? If so how would we know and identify them, eg that they have particular features uncommon in most Sapiens?
Sorry I posted this same question moments ago but in the wrong thread.

Not new species per se, but certain human traits and genetic variances are more recent than others. The ability to digest lactose in adults is thought to be a recent development, for instance (https://doi.org/10.1038/500020a). A trend happening in the past couple centuries or so is increased presence of the medial artery (https://doi.org/10.1111/joa.13224).
