It is true that the number and diversity of marine life is much greater than that found on Earth. But compared to the earth, the number of insects in the sea and ocean is very less. Japanese scientists claim to have found the reason for this. According to the scientist, the worm works in a kind of chemical system, and it helps them to make a shell for themselves, which is very useful on earth but not suitable for the marine environment.
Scientists say that a specific type of MCOTU enzyme is responsible for this. This enzyme helps to harden the insect’s shell and this is the reason why the number of insects is not high in the marine environment. While due to this characteristic, insects have established themselves as successful creatures on earth.
This concept has been proposed by scientists from Tokyo Metropolitan University in Japan. Earlier, they showed that insects develop a special chemical system to harden their shells, and for this they use molecular oxygen and the multicopper oxidase-2 (MCOTU) enzyme.
The scientific argument is that this system harms insects in marine life, while it benefits insects that live on land. MCiotu is considered the life of insect development. Insects are said to be one of the most successful organisms on the planet. It is the food of many animals of the earth and it has a profound effect on the global ecosystem. But even though it is so important, what is surprising is that the ancestors of insects are from the sea. Now its numbers are negligible in the metropolis, while on earth it is abundant and plays a major role in many ecosystems. This puzzle has been puzzling scientists for a long time, but scientists led by Sunki Asana have found an answer to this question on the basis of genetic evolution.
Recent molecular phylogenetics has revealed that both crustaceans and worms belong to the same family Pancrustacea. The insect is the branch that left the sea and settled on the earth. But both have a layer of wax on the outer covering and have a tough cuticle. Earlier, the team showed that by the time insects arrived on Earth, they had developed a gene that produces an enzyme called MCOTU.
The worm works to strengthen the cuneicle by using MCOTS oxygen. MCOT mediates a reaction when molecular oxygen oxidizes catecholamine compounds in the epidermis and hardens its shell. Crustaceans, on the other hand, hardened their shells with calcium from seawater. This was the reason that the land is more suitable for insects.
