Mass extinctions reshape the biosphere — and recovery from them looks different every time. A guide to the Big Five, what caused them, and why some scientists think we're in the middle of a sixth.Tue, 12 May 2026 00:00:00 GMTBiologyevolutionnatural historybiodiversityecologyhttps://biologycontest.com/posts/mitosis-and-meiosis-how-cells-divide/https://biologycontest.com/posts/mitosis-and-meiosis-how-cells-divide/Mitosis copies a cell. Meiosis halves it. The two kinds of cell division do completely different jobs in your body — one builds and repairs, the other makes the eggs and sperm that pass DNA to the next generation.
