How did Jupiter’s gravity influence the growth of the terrestrial planets?

According to the "Grand Tack" hypothesis, Jupiter’s gravity significantly influenced the formation and final characteristics of the terrestrial planets through its inward and outward migration early in the solar system’s history.12

As Jupiter migrated inward toward the Sun, its immense gravitational influence perturbed the orbits of material in the inner solar system, making them more elliptical. This process cleared away much of the material that would have otherwise been available for the growth of the terrestrial planets. Specifically, this migration is believed to explain the relatively small size of Mars, which might have grown much larger had that material remained accessible.321

Furthermore, computer models suggest that if any "super-Earths" (large rocky planets) had begun to form in the inner region, Jupiter’s gravitational interference would have caused them to collide with other perturbed material and fall into the Sun within tens of thousands of years, potentially explaining why our solar system lacks such planets today.3
