Which of the following would be the best inference drawn from these observed changes in hominid skulls? O Earty hominids had larger brains and were able to develop a method for bipedal movement
Early hominids needed smaller brains than modern humans to help them create and use simple tools
O Early hominids with smaller jaws passed on those genes for smaller jaws more frequently than those with larger jaws.
Early hominids were the top predator so they were not subjected to any evolutionary forces, and therefore have not undergone any evolutionary changes.

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers

"it built up in the atmosphere"
