In 2014, a study discovered a new mtDNA subclade C1f from the remains of three people found in north-western Russia and dated to 7,500 years ago. It has not been detected in modern populations. The study proposed the hypothesis that the sister C1e and C1f subclades had split early from the most recent common ancestor of the C1 clade and had ...
Prehistoric fish are early fish that are known only from fossil records. They are the earliest known vertebrates, and include the first and extinct fish that lived through the Cambrian to the Quaternary. The study of prehistoric fish is called paleoichthyology. A few living forms, such as the coelacanth are also referred to as prehistoric fish ...
An unassuming freshwater fish contains the longest genomic sequence ever discovered, measuring in at 30 times the length of the human DNA chain. Researchers found that the South American lungfish ...

The first fish lineages belong to the Agnatha, or jawless fish. Early examples include Haikouichthys.
