What evidence supports the hypothesis that the nuclear envelope of eukaryotes arose from infolding of the plasma membrane?

The endoplasmic reticulum (ER) and nuclear membrane of modern eukaryotes are continuous.

Explanation:

The evidence of the hypothesis that nuclear envelope of eukaryotes originates from the infoldings of the plasma membrane.

The nuclear membrane and the endoplasmic reticulum of the eukaryotic cells are continues in nature. They are made of protein which are infolded because there is not much space inside the cell so the things inside are either condensed or infolded.
