Before making this statement, 159 bones of the Moa bird species, which lived in New Zealand, have been analyzed according to the data provided. As has been observed, a DNA molecule loses 50% of its properties every 521 years, and it is estimated that nothing will remain after 65 million years.
A group of researchers from the University of Texas (USA) has analyzed the vocalization of current birds in order to infer the sounds produced by their dinosaur ancestors. “The results show that oral vocalization has evolved up to at least sixteen archeosaurs (the group... [+]

Since his bones were found in Ethiopia in 1974, Lucy (in the photo) has been considered our oldest ancestor. The remains of Australopithecus afarensis are 3.2 million years old. There were 52 bones of a woman about twenty years old and barely a meter, 40% of the skeleton, which... [+]
