Science/Nature | Extinction Threat to Wild Salmon
Science & Tech  (tags: fish, wild salmon, extinction, bears, parasites )

- 2315 days ago -
Wild salmon on Canada's west coast are being driven to extinction by parasites from nearby fish farms.Sea lice from farms are known to infect wild salmon,the probability of extinction is 100% and the only question is how long it is going to take.
Fish Give Clues to Human Skin Color Changes
Science & Tech  (tags: skin color, fish, humans, Kit gene ligand, gene variant )

- 2315 days ago -
Scientists found that the lighter fish had mutations in a gene called Kit ligand. The researchers then analyzed DNA from people with different skin colors and found that those with lighter skin also had an altered form of the Kit ligand gene.

Science & Tech  (tags: science, research, animals, fish, Canada, extinction, interesting )

- 2316 days ago -
Infestations of sea lice at salmon farms on Canada's west coast are threatening local wild pink salmon populations and could result in their extinction in another four years.
Oral Sex Gene Helps Male Fish Fake It
Science & Tech  (tags: fish, eggs, sperms, fertilization, gene, mating, science )

- 2343 days ago -
As soon as a female has spawned her eggs, she collects them up in her mouth. Males of certain cichlid species in east Africa have evolved a way to increase the odds that females take up their sperm. A gene called csf1ra was responsible.
First Land Animals Would Have Wanted a Color TV
Science & Tech  (tags: Australian, lungfish, visual pigment, tetrapods, fish, ultraviolet )

- 2361 days ago -
The retinas of Australian lungfish contain visual pigment genes that are more similar to those of tetrapods -- four-legged land animals with backbones -- than those of other fish. They also found evidence the fish can see in ultraviolet.
Humans Have Fish to Thank for Their Hands and Feet
Science & Tech  (tags: fish, humans, digits, vertebrates, evolution, genes, science )

- 2371 days ago -
Land animals owe the development of their limbs to a gene that helped in the evolution of fins in a primitive fish. Scientists found that one of its fin-sprouting genes of Australian lungfish also guided the growth of digits in land vertebrates.
