Scientists used special technology to sequence DNA and have declared that the Australian lungfish is the closest living relative to humans that is currently alive.
The lungfish has existed for 400 million years and have not evolved in the last 100 million years. Scientists call it a “living fossil.” Lungfish can breathe air and use its fins like limbs, which can explain the evolution of animal life on land. Scientists want to study their natural habitat to put together more of this story.
Lungfish are a protected species. They can be mistaken for crocodiles because they can grow to up to 2-meters.
