large planetesimals gobbled up smaller ones and asteroids

An example of anrthropomorphism in popular science writing:

"The time period of the planetesimals was one of 'survival of the fittest'. They had to jostle for an orbit in space and cataclysmic collisions were still common that, in some cases, completely blew them to pieces. Eventually the chief planetesimals gobbled up smaller ones as well as asteroids in their path, to grow into even larger objects. These became the rocky planets we see today. The planets established themselves as the leaders of the pack, gravitationally excavating their clean orbit around the Sun."
