As detailed in our newly published paper, what we found shows that previous examples of mobility were not the first on the planet. In fact, we have found proof of locomotion on Earth 2.1 billion years ago – much further back than previous evidence of single cell organisms alone, let alone...

A report on the questioning of existence of life in the most ancient rocks on earth and elsewhere in the solar system is presented. Greenland is home to rocks harboring well-accepted evidence that living cells existed on earth more than 3.7 billion years ago, only several million years after...
” From a population-based perspective, the transitional threshold between the third age and the fourth age is the chronological age at which 50% of older adults are no longer alive (Baltes and Smith2003). In a few cases, researchers have also used the term to refer to centenarians (Poon ...
