New Discovery in Brazil Shows Earliest Evidence of Evolutionary Adaptation
A new fossil discovered in Brazil is providing the earliest evidence of the evolution of mammals, according to a new study by paleontologists from the Federal University of Rio de Janeiro. The fossil, which dates back to the Late Triassic period, some 230 million years ago, belongs to a small mammal that lived in the rainforests of Brazil. This is the first time that an animal of this age and size has been found in the Americas. The fossil provides invaluable insight into the evolution of mammals, and indicates that they had already evolved a very early form of locomotion and were beginning to diversify. This discovery is set to revolutionize our understanding of mammalian evolution.
