When there was only one land mass, is there any scientific theories if that would change the rotation of the earth on its axis or around the sun?
It would not. The mass of the Earth doesn't change, and angular momentum is conserved.
I was curious since mass would seem lopsided. I guess not enough. Thanks for answering.
My layman's understanding is that the water mostly makes up for it, and that more wobble comes from the moon than any inconsistency in land-mass distribution
No, but the climate was probably cooler and drier than today. In fact the interior regions of the supercontinent might have been too dry to support most life-forms.
