If the comet hit all that time ago was so big how come humans and monkeys survived but things as big as dinosa

Question

urs got killed

Answer 1

When something large hit the earth about 65 million years ago, causing devastating climate change the killed the dinosaurs and many other species, there were no "humans and monkeys" around. People have only been around a very short time.

The mass extinction (one of several in Earth's very long history) is believed to have interrupted plant growth by blocking the sun with clouds of debris. Plants died. The dinosaurs that ate them starved. The meat-eaters who fed on them did likewise. Cooling temperatures did in most cold-blooded creatures (dinosaurs, etc.). Small warm blooded creatures that didn't eat too much, like early mammals, survived and flourished once the skies cleared. A long while later, some evolved into humans and monkeys.

Answer 2

Actually, it was the dinosaurs' size that was their undoing. Large creatures such as they were required LOTS of food to sustain them. The problem was not just the blast wave of the impact itself. The REAL problem caused by the impact was the global cooling that followed. All the dust and debris thrown up into the atmosphere blocked out the sun for a long time afterwards. Lots of vegetation would have died.

This means there was a lot less food available, and the larger creatures would have not been able to survive the change in habitat and loss of food.

Mamals are better-adapted to cold climates than are reptiles, since their own bodies generate heat whereas reptiles require external heat sources to help give them energy. It was this impact that in fact opened the door for mamals to become the dominant life forms on the planet with the dinosaurs now out of the way.

Answer 3

Because dinosaurs died out about 65 million years ago, while modern Homo Sapiens have only been around about 200,000 years or so. So they didnt exist on the planet at the same time.

As for things surviving the impact 65 million years ago, you said it yourself, it killed the big things. Small animals, particularly the smaller mammals we are thought to have evolved from, were able to hide in burrows or other various ways during the nuclear winter that followed the impact, plus the fact that being smaller, they dont have to eat as much! So the food shortage during that time wasnt enough to wipe out the smaller animals, only the larger ones.

Answer 4

Not too friggin bright are you Britsrule?.. and certainly not a student of history. The dinosaurs lived 65 million years ago. Mammals such as monkeys, apes and man didn't appear until millions of years after the catastrophe. Man only appeared about 6 million years ago.

Answer 5

The theory is that humans, monkeys, and oter mamals did not even exist at that time.

there is absolutely o evedince that dinosaurs existed at the same time as humans and higher mamals.

Answer 6

they did not co exsist
