Female fish can beget a new species if they aren’t fussy about who is Mr. Right.
According to new research, fish will mate with a species outside of their own if the coloring of the male is fascinating enough or if the female can’t see the male fish correctly. Such mistakes in mate choice conduct the manifestation of new species, an international team of scientists has discovered. The group studied 2000 fishes and resolved the DNA of more than 400 cichlid fish from two freshwater lakes in East Africa. The researchers unfolded more than 40 new species in Lake Mweru, that was formed about one million years ago.
Dr. Joana Meier, who is an evolutionary biologist at St John’s College, University of Cambridge, and the lead author of the research of the study that was published in Nature Communications, have stated that they have found a glaring variety of ecologically various new species, called radiations and it was unknown previously. The new species of cichlids adapted to apply all the attainable food resources in the lake. Some feed on insect level, and others feed on zooplankton or algae. Some newly revealed fish are predators with massive teeth that the researchers named large-tooth serranchromines. Many people believe fish are all the same species as they all live in water. But there are 30,000 various species of fish, and many of them are notably different from each other. Hoping them to mate outside of their species is like expecting a horse to mate with a cat as they both have four legs and a tail.
Fossil record displays that fish have subsisted for more than 500 million years that makes them very old on the evolutional scale. There are over 1300 species of cichlids, and many are famous aquarium fish. They are initially freshwater fish, and the majority of species are African, arriving in great variety in the major African lakes where this study of 10 years took place. Female cichlid fish select their partners. In mating ritual tests in the lab, the team of international scientists revealed that under particular circumstances, the females would choose a male of various species that had the same coloring to males from their species.
