What are oldest life forms on earth?
In its 4.6 billion yearscircling the sun, the Earth has harbored an increasing diversity of life forms:for the last 3.6 billion years, simple cells(prokaryotes);for the last 3.4 billion years, cyanobacteriaperformingphotosynthesis;for the last 2 billion years, complex cells(eukaryotes);for the last 1.2 billion years, eukaryotes which sexually reproducefor the last 1 billion years, multicellular life;for the last 600 million years, simple animals;for the last 550 million years, bilaterians, water life forms with a front and a back;for the last 500 million years, fish and proto-amphibians;for the last 475 million years, land plants;for the last 400 million years, insects and seeds;for the last 360 million years, amphibians;for the last 300 million years, reptiles;for the last 200 million years, mammals;for the last 150 million years, birds;for the last 130 million years, flowers;for the last 60 million years, the primates,for the last 20 million years, the family Hominidae(great apes);for the last 2.5 million years, the genus Homo (human predecessors);for the last 200,000 years, anatomically modern humans.Periodic extinctions have temporarily reduced diversity, eliminating:2.4 billion years ago, many obligate anaerobes, in the oxygen catastrophe;252 million years ago, the trilobites, in the Permian-Triassic extinction event;66 million years ago, the pterosaurs and nonavian dinosaurs, in the Cretaceous-Paleogene extinction event.all dates are approximate
The cells in your body are continuously disassembled and reassembled what kind of body cells last the longest?
neurons
How long do cells in your body last?
It varies dramatically depending on what type of cell it is. For example, blood cells and skin cells are constantly being replaced, so they don't live for very long. However, your brain and nerve cells NEVER get replaced, so they live until you die. That's why if you hurt your spine in, for example, a car wreck, you are likely paralyzed for life, whereas if you scrape your skin it will grow back.
