Interspecies Mating Between Blue and Fin Whales More Common Than Previously Thought

New research has revealed that North Atlantic blue whales have around 3.5 percent of their DNA from fin whales, suggesting that interspecies mating between these two whale species may be more common than previously thought. The study has also shown that the offspring of blue and fin whales appear to be fertile, challenging conventional understanding of hybrid animal fertility. This groundbreaking discovery provides valuable insights into the genetic dynamics of whale populations and raises intriguing questions about the potential impact of interspecies breeding on the evolutionary trajectory of these magnificent marine creatures.

Mitonuclear incompatibility in swordtail fish sheds light on speciation mechanisms

The evolution of reproductive barriers is the first step in the formation of new species and can help us understand the diversification of life on Earth. These reproductive barriers often take the form of hybrid incompatibilities, in which alleles derived…
