Is it true that Earth and Mars formed from materials with different origins in the early solar system?
Unclear. Two peer-reviewed modeling studies partially support the claim: one reports Earth accreted more chondrules and less matrix-like material than Mars, and another finds the terrestrial planets accreted mostly locally with distinct feeding zones and distinct isotopic compositions. Neither directly states that Earth and Mars formed from materials with different origins as a general conclusion.
