Question

If duration of existence on Earth was considered the ultimate indicator of success, which species would be the most successful by this measure?

dinosaurs
human beings

Answer 1

Dinosaurs

Step-by-step explanation:

Dinosaurs lived 165 million years, before going extinct about 65 million years ago. Humans are assumed to have lived somewhere between 7 to 2 million years ago. 165 million > 7 million, so dinosaurs would be more successful.

Answer 2

Answer: Dinosaurs

Step-by-step explanation:

Dinosaurs lived on earth for around 165 million years while humans have only been around for at most, 7 million years or so. So dinosaurs, as a species, have lived longer on the earth even thought they are now extinct.
