The Argonians were tree-dwelling lizards that were changed by the Hist to be their protectors and moulded in the image of Mer, Khajiit were Mer that were blessed by Azura with their feline forms.

Regarding Giants, it's difficult to say what their origins are. It's speculated that they originate from Atmora, as the King of Atmora during Talos' visit during the Second Era was of giant size and stature. Quite possibly old Atmorans were large in size, with those who would become the Nords gradually losing their size and those that would become Giants gradually losing their intelligence.
