Explanation:

Mammoth, (genus Mammuthus), any member of an extinct group of elephants found as fossils in Pleistocene deposits over every continent except Australia and South America and in early Holocene deposits of North America.

• The woolly, Northern, or Siberian mammoth (Mammuthus primigenius) is by far the best-known of all mammoths.
• The relative abundance and, at times, excellent preservation of this species’s carcasses found in the permanently frozen ground of Siberia has provided much information about mammoths’ structure and habits.
• It is believed that mammoths disappeared because of a change in climate, disease, hunting by humans, or perhaps some combination of these.
• De-extinction of Woolly Mammoths can lead to:
• Restoration of Ecosystem: When mammoths disappeared from the Arctic some 4,000 years ago, shrubs overtook what was previously grassland.
• Mammoth-like creatures could help restore this ecosystem by compressing shrubs, knocking over trees, and fertilising grasses with their faeces.
• Reduce Climate Change: If the current Siberian permafrost melts, it will release potent greenhouse gases.
• De-extinction will prevent the permafrost from melting. Compared to tundra, grassland might reflect more light and keep the ground cooler.
• The CRISPR gene editing technology will be used to modify Asian elephant embryos.
• Asian elephants are the mammoth’s closest living relative so their genomes resemble those of woolly mammoths.

Hence all statements are correct.
