What kinds of organisms lived before humans appeared on Earth?

Answer 1

Let's think about this for a minute- you are asking what things were like before anyone was there to observe what things were like. There may be a problem with that- since it would be impossible to know for certain.

Answer 2

Before humans appeared on Earth, a wide variety of organisms inhabited the planet, including dinosaurs, early mammals, marine life such as fish and sharks, insects, plants, and microbes. These organisms played important roles in shaping the environment and ecosystems that eventually led to the emergence of humans.

Answer 3

Humans evolved from a long line of hominids

Homo Habilus & Homo Erectus to name a couple

(not sure those names are spelled exactly right, but you can look them up)

AnswerActually , humans didn't came into existence because of revolution . We , Muslims , believe that GOD ( Allah ) created humans from clay and water , thousands of years ago .

Answer 4

This is a matter of opinon and the answer depends on wether you believe the evolutionist's theory or the religious one. Coming from an atheist's veiwpoint I believe that there is more proof that humans have evolved from other creatures (like ape) and I think it is highly unlikely that we were created by God

Another answer.

Scientists believe that apes and other primates mated and created humans. That is just a theory, because Lord created the first man on Earth, Adam. Then Lord gave Adam a wife, Eve. They mated and had many children who developed and developed for generations. This is not religious as some may say. It is the truth. No two species had ever mated to create human. Why do we speak? Why don't we have large mouths and large jaws and oppasable thumbs on our feet like an ape does??

Answer 5

Jellyfish were the first living thing on Earth (beside bacteria). And today is the longest surviving living thing on Earth.

Jellyfish eventually evolved into small marine creatures, fish and then reptiles.

Answer 6

People believed firmly in religious doctrines stating theories of intelligent design until approximately the 18th century, when the a small number of European scientists began to quietly suggest that life forms are not fixed. It was suggested at first that organisms changed form to suit their environment and passed these acquired traits on.

Answer 7

Animals did come first because God made them first. He then made man on the sixth day.

Answer 8

A vast array of animals and plants, and several species of hominid that weren't quite human

Answer 9

Every type. The first animals ever were small bacteria, then fish and reptiles, then dinosaurs and amphibians, then birds and mammals, then humans. Humans are the last animals to evolve.

Answer 10

Microorganisms
