Eastern Lowland gorilla species that have been threatened with loss of genetic diversification and are now threatened by other problems – dangerous genetic mutations. At least that is the conclusion reached by an international team of scientists who listed 11 100-year-old genomes from Eastern gorilla specimens.
Over the past 100 years, many species on Earth have decreased in number, and scientists have believed that the loss of genetic diversification is behind this threatening situation. Now, we have confirmation that indeed genetic mutations are behind at least a decrease in one of the most threatened species on the planet, the Eastern Lowland gorilla.
"We found that genetic diversity in Grauer gorillas has declined significantly in just a few generations," said Tom van der Valk, Ph.D. student at Uppsala University in Sweden, quoted by EurekAlert.
The Eastern Lowland gorilla species live in the Democratic Republic of the Congo and "have declined by 80 percent in recent decades due to hunting and habitat destruction," EurekAlert reported.
Genetic Mutations Are Dangerous To Endanger Eastern Lowland Gorillas Even More Than Hunting And Destruction of Habitats
Genomic sequencing carried out by scientists revealed that an increase in marriage led to a loss of genetic diversification, which means that lowland gorilla species in the Highlands are now increasingly threatened by the dangerous genetic mutations they develop.
"Recent dangerous mutations strongly emphasize the need to reverse the ongoing decline of the Grauer gorilla population," explained Love Dalan of the Swedish Natural History Museum.
"Our study highlights that historical museum specimens are a unique resource for monitoring the latest changes in the genetic status of endangered species," added Katerina Guschanski of Uppsala University.
In conclusion, Eastern Lowland gorillas, a species that has been threatened by poaching and habitat destruction, are now even more threatened by the dangerous genetic mutations that specimens have developed due to increased cross-breeding, according to a new study.
