How long does it take new species to form on earth? how long does it take new species to form on earth? the time required varies considerably. speciation no longer takes place on earth. millions of years submit?

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

not always but somethings can be reproduced in a laboratory.
