Jellyfish evolution

Evolution and Origins. The Kavli Institute researchers have found out that the moon jellyfish’s metamorphosis was achieved without any major genetic mutations, but by utilizing a subset of pre-existing genes to transform from polyp to medusa, instead of the conventional process of mutation and natural selection.

In a home lab Varma has been raising moon jellyfish (Aurelia aurita).Many jellyfish species are known to cause a painful sting, but box jellyfish (class Cubozoa) are a well-known danger to humans due to exceptionally potent venoms. Cubozoan toxicity has been attributed to the presence and abundance of cnidarian-specific pore-forming toxins called jellyfish toxins (JFTs), which are highly hemolytic and cardiotoxic.

Why the tiny jellyfish evolved the ability to be immortal and we didn’t, even though many scientists think we should be able to be immortal or at least have the ability to rejuvenate our bodies forever? Well, this is just one the many mysteries of evolution…but this one is more puzzling than the previous 4 I have posted…at least to me….

Apr 5, 2023 · Evolution and Origins of Jellyfish Belonging to the phylum Cnidaria, which also encompasses corals and anemones, jellyfish originate from one of the earliest branches of the animal kingdom. They were likely among the first creatures to swim through the open ocean using muscular power. As to why jellyfish sting an estimated 150 million people each year when humans are not its prey, the best answer is still likely a defense response. It could also lie in our chemical makeup, however. “This comes back to which chemicals are sensed,” Bellono said. “Is the animal adapted to very broadly sense some generalized chemical that ...Oct 28, 2020 · These bizarre ancient species are rewriting animal evolution.
