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.

What is the first creature?
World's first animal was a pancake-shaped prehistoric ocean dweller. Fossils of ancient sea creatures answer a long-standing question about how animals became bigger and more complex. The strange sea creatures known as Dickinsonia, shown here in fossil form, lived 558 million years ago.
What was the first thing to ever exist?
Scientists believe LUCA organism is the first thing to have ever lived on Earth. The Earth is more than four billion years old, and so is LUCA — the first thing to ever live on it.
Who came first on Earth?
About 1.9 million years ago, Homo erectus evolved. This human ancestor not only walked fully upright, but had much larger brains than Homo habilis: nearly twice as large, on average.
What animals were alive before dinosaurs?
Animals included sharks, bony fish, arthropods, amphibians, reptiles and synapsids. The first true mammals would not appear until the next geological period, the Triassic.
What were the first living things on Earth?
Some scientists estimate that 'life' began on our planet as early as four billion years ago. And the first living things were simple, single-celled, micro-organisms called prokaryotes (they lacked a cell membrane and a cell nucleus).
How old is the earth?
Earth is estimated to be 4.54 billion years old, plus or minus about 50 million years. Scientists have scoured the Earth searching for the oldest rocks to radiometrically date. In northwestern Canada, they discovered rocks about 4.03 billion years old.
When was the Earth born?
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.
What created the universe?
Our universe began with an explosion of space itself - the Big Bang. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies.
Can dinosaurs come back?
The answer is YES. In fact they will return to the face of the earth in 2050. We found a pregnant T. rex fossil and had DNA in it this is rare and this helps scientists take a step closer of animal cloning a Tyrannosaurus rex and other dinosaurs.
What dinosaur is still alive?
Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive. These, and all other non-avian dinosaurs became extinct at least 65 million years ago at the end of the Cretaceous Period.
Are cockroaches older than dinosaurs?
You already know roaches never die. These insects were one of the most dominant species during the Carboniferous period -- which took place about 360 million years ago (or 112 million years before the dinosaurs) -- and they were about twice as big as their current form.
How old is Moon?
Scientists looked to the moon's mineral composition to estimate that the moon is around 4.425 billion years old, or 85 million years younger than what previous studies had proven.
How long will the earth last?
By that point, all life on Earth will be extinct. The most probable fate of the planet is absorption by the Sun in about 7.5 billion years, after the star has entered the red giant phase and expanded beyond the planet's current orbit.
Will the universe end?
Astronomers once thought the universe could collapse in a Big Crunch. Now most agree it will end with a Big Freeze. ... Trillions of years in the future, long after Earth is destroyed, the universe will drift apart until galaxy and star formation ceases.
How old is the human race?
While our ancestors have been around for about six million years, the modern form of humans only evolved about 200,000 years ago. Civilization as we know it is only about 6,000 years old, and industrialization started in the earnest only in the 1800s.
How did Earth get its name?
The name Earth is an English/German name which simply means the ground. ... It comes from the Old English words 'eor(th)e' and 'ertha'. In German it is 'erde'.
