Who was dinosaur
Answers
Explanation:
(1) . Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula. Volcanic outgassing probably created the primordial atmosphere and then the ocean, but the early atmosphere contained almost no oxygen. (2). Modern humans, along with other great apes, evolved from a common ape-like ancestor. Early humans evolved around 7 million years ago. Over the past 7 million years, there have been over 20 different species of early humans. ... Our ancestors evolved in Africa and stayed there for three to four million years.(3) No dinosaurs are not alive in this era . (4) . Dinosaurs were a successful group of animals that emerged between 240 million and 230 million years ago and came to rule the world until about 66 million years ago, when a giant asteroid slammed into Earth. During that time, dinosaurs evolved from a group of mostly dog- and horse-size creatures into the most enormous beasts that ever existed on land.
