However, full-fat cheeses are not your friend, since these foods typically contain hefty amounts of artery-clogging saturated fatâup to 6 grams in just one ounce of full-fat cheese (the size of a pair of dice!) Thatâs about one third of the total saturated fat recommended for good health in a single day.
The Earth formed 4.5 billion Years ago. The Earth was a dead planet for about 1 biâ¦llion years. Some evidence would suggest that the first forms of life began more like 3.8 billion years ago, in which case the Earth was dead only 700 million years. The study of the processes which resulted in the beginning of life is called Abiogenesis.
Life on Earth first appeared as early as 4.28 billion years ago, soon after ocean formation 4.41 billion years ago, and not long after the formation of the Earth 4.54 billion years ago. Earth's current life may have descended from an RNA world, although RNA-based life may not have been the first. The mechanism by which life began on Earth is unknown, though many hypotheses have been formulated and are often based on the MillerâUrey experiment.
