What was the first species to live on Earth?
Earth’s first animal was the ocean-drifting comb jelly, not the simple sponge, according to a new find that has shocked scientists who didn’t imagine the earliest critter could be so complex. The mystery of the first animal denizen of the planet can only be inferred from fossils and by studying related animals today.
Did animals exist before humans?
Mammals rose to prominence in the aftermath, with the first humans arising less than 1 million years ago. Giant reptiles, ammonites, and large classes of plants and animals all existed prior to that event, along with small, flying birds and the tiny, land-dwelling mammals. After that event, the mammals survived.
How old was the first life form on Earth?
The earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old. The signals consisted of a type of carbon molecule that is produced by living things.
When did the first animals appear on Earth?
Almost 600 million years ago, multicellular life forms started appearing. Scientists are confident that some of the species can be considered the first animals on Earth.
What was the first animal to live under the sea?
Lemurs, gibbons, bonobos, orangutans, gorillas, and even modern humans are all linked to this point in the timeline of life on earth. Around 50 million years ago, whales evolved to live under the sea. The earliest forms of these are thought to have been land animals adapting to life in the sea.
Which is the oldest living thing on Earth?
These bacteria are believed to be the Earth’s oldest known life form. Fossilized stromatolites – a type of layered rock made up of microbial mats of microorganisms – dating back to over 3.5 million years ago contain evidence of cyanobacteria activity.

What was the first animal discovered on Earth?
Not only have MIT biologists discovered the very first animal on Earth, they’ve found that it existed 250 million years earlier than previously thought. New research shows that the simple sea sponge was the very first animal on Earth.
