The first detected quakes on Mars suggest that the Red Planet has a larger core, potentially thinner crust and slightly different composition than scientists had thought.

""These observations have fueled speculation that Mars might represent a stranded planetary embryo that depicts the chemical characteristics of the solar nebula [the gas and dust that birthed the sun and planets] at the location of the orbit of Mars," Khan said."

I appreciate the alternatives, but is there a possibility that the large core has similarities to Mercury, in that it results from impact and loss of mantle? Might the lower density and different composition has resulted from more mixing after impact?

Any ideas?
