Why hasn’t coelacanth evolved?
The genes of the coelacanth have a lower rate of “substitution” – a type of mutation – than other animals with backbones, which may reflect the fact that they do not need to evolve quickly because they live in the relatively unchanging environment of deep-sea caves where there are few predators, the researchers say.
How did the coelacanth survive extinction?
Like all fish, today’s species of coelacanths use gills to extract oxygen from the water they live in. This could explain how it survived the extinction event 66 million years ago that wiped all non-avian dinosaurs and most other life from Earth — and probably those coelacanths inhabiting shallow waters, Dr Brito said.
Are coelacanths extinct?
Not extinct
Coelacanth/Extinction status
Are coelacanth still alive?
Coelacanths reside at ocean depths of as much as half a mile (800 meters). The two extant species, both endangered, are the African coelacanth, found mainly near the Comoro Islands off the continent’s east coast, and the Indonesian coelacanth.
Does the coelacanth disprove evolution?
If you bother to read the awful article, it includes a standard creationist canard: Coelacanths haven’t changed a bit over their long history, and this disproves evolution. Well, this fish apparently forgot to evolve for 65 million years! You see, the living coelacanth is easily recognizable from the fossils.
Why is the coelacanth called a missing link?
The coelacanth is special among all those fossils hailed as “missing links” because it suddenly emerged as a live specimen off the coast of East Africa in 1938. In 1839, the Swiss scientist Louis Agassiz described the fossil of an unusual fish tail found in the north of England.
What is the oldest fish still alive?
coelacanth
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.
How do coelacanths mate?
The females lay their eggs in a quiet spot in their aquatic environment; subsequently, the males — it can be several — add their semen. The offspring grow up in the water without their parents’ protection — whereas the coelacanth gives birth to fully developed young.
