Now 220+ mini preschool learning Games for kids, all in one app. “Many of the traits that breeders are selecting are regulated by very few genes that have a major effect,” Ms. If you can imagine it, it probably exists. There are red, yellow and blue bettas, bettas with big fins and small fins and even bettas that resemble Thailand’s flag. The research also highlighted why breeders have been able to create dozens of different varieties of betta. That is further back than earlier anecdotal research cited in the study suggesting that bettas had been bred for fighting as early as the 13th century. “We were surprised by how long bettas have been part of human history - it’s been domesticated for at least 1,000 years, making it one of the oldest fish domestications known,” said Ms.

Kwon and a team of scientists collected DNA samples from wild and domestic betta and sequenced their genomes. /rebates/2fhighlights-shapes&. To determine exactly how this history shaped the ornamental bettas we see today, Ms. “This history has shaped the ornamental bettas we see today - a really beautiful fish with a temper,” she said. By studying the genes of these fish, the study’s authors argue, scientists can learn a great deal about how domestication alters the genes of wild animals.īy the end of the 19th century, breeders began focusing on creating ornamental varieties of the fish, which had become extremely popular in the West. The millennium of careful selection gave rise to the stunning diversity of domestic betta fishes alive today, but also caused both wild and domestic betta fish to undergo vast genetic changes. Or as Yi-Kai Tea, a doctoral candidate at the University of Sydney who studies the evolution and speciation of fishes, put it, “quite literally the fish equivalent of dog domestication.”Ī new study, uploaded in April to the preprint service BioRxiv, shows through genome sequencing that humans began domesticating bettas at least 1,000 years ago. The betta’s elaborate colors and long, flowing fins are the product of a millennium of careful selective breeding. However, bettas, also known as the Siamese fighting fish, did not become living works of art on their own.
