Since the extinction event that wiped out the dinosaurs 66 million years ago,
fish have evolved and diversified
, leading to the wide variety of fish species we see today.
What fish has been around since the dinosaurs?
Synopsis.
Coelacanths
, which have been around for 400 million years, were thought extinct until they were found alive in 1938 off South Africa. The coelacanth a giant weird fish still around from dinosaur times can live for 100 years, a new study found.
What did fish evolve from?
Fish may have evolved from
an animal similar to a coral-like sea squirt (a tunicate)
, whose larvae resemble early fish in important ways. The first ancestors of fish may have kept the larval form into adulthood (as some sea squirts do today), although this path cannot be proven.
Did humans originate fish?
There is nothing new about humans and all other vertebrates having evolved from fish
. The conventional understanding has been that certain fish shimmied landwards roughly 370 million years ago as primitive, lizard-like animals known as tetrapods.
The closest living relatives of Tyrannosaurus rex are birds such as chickens and ostriches
, according to research published today in Science (and promptly reported in the New York Times). Paleontologists used material discovered in a chance find in 2003 to pin down the link.
Are dinosaurs still alive in 2021?
In an evolutionary sense, birds are a living group of dinosaurs because they descended from the common ancestor of all dinosaurs. Other than birds, however,
there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive
.

480 million years ago
, when fish are believed to have first appeared.
Why did fish evolve bones?
The first bones containing living cells provided key minerals that allowed the fish to undertake longer journeys–changing the trajectory of vertebrate evolution.
Did humans evolve from fish or apes?
There’s a simple answer:
Humans did not evolve from chimpanzees or any of the other great apes that live today
. We instead share a common ancestor that lived roughly 10 million years ago.
Did humans have a tail?

humans and apes lack a visible tail
, they share a tiny set of vertebrae that extend beyond the pelvis — a structure known as the coccyx.
How would humans look like in 1000 years?
Humans and zebrafish share
70 percent
of the same genes and 84 percent of human genes known to be associated with human disease have a counterpart in zebrafish. Major organs and tissues are also common. Zebrafish genome has also been fully sequenced to a very high quality.
Is an alligator a dinosaur?
Alligators are not dinosaurs
, though they belong to the same order as dinosaurs once did. Their ancestors were closely related to dinosaurs and walked the earth at the same time. While dinosaurs went extinct, alligator ancestors went on to evolve into the alligators we see on Earth today.
Do chickens have dinosaur DNA?
Chickens are actually direct – albeit petite – descendents. As a result,
chicken DNA is surprisingly most closely related to dinosaur DNA

Of course, it wouldn’t be Thanksgiving without surprises from relatives — and
turkeys certainly have surprising relatives: meat-eating theropod dinosaurs like Tyrannosaurus rex
. In fact, Tyrannosaurus rex, the king of the dinosaurs, and living turkeys shared a common ancestor about 190 million years ago.
Will dinosaurs be coming back?

it has been predicted that humans will be able to bring dinosaurs back from extinction in some capacity by 2050
.
Can dinosaurs come back in 2050?
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.

Can fish live for 100 years?
The coelacanth — a giant weird fish still around from dinosaur times — can live for 100 years

What is the dinosaur fish called?
Due to its massive size and the fact that its virtually unchanged in the fossil record for 23 million years, DeSouza says
the arapaima

What is the oldest thing in the universe?
Microscopic grains of dead stars
are the oldest known material on the planet — older than the moon, Earth and the solar system itself. By examining chemical clues in a meteorite’s mineral dust, researchers have determined the most ancient grains are 7 billion years old — about half as old as the universe.
