Significant volcanic activity or a sudden increase in greenhouse gases, such as carbon dioxide, most likely caused the giant ice caps of the Paleozoic era to melt. These events would have led to a rapid warming of the climate, resulting in the melting of the ice caps.
During the Paleozoic era, the Earth experienced significant fluctuations in climate due to factors such as variations in the Earth's orbit, volcanic activity, and changes in greenhouse gas levels. These fluctuations likely led to the melting of the giant ice caps that existed at that time.
A significant increase in greenhouse gases, such as CO2, and a rise in global temperatures would have most likely caused the giant ice caps of the Paleozoic era to melt. This could have been triggered by volcanic activity releasing large amounts of CO2 or natural climate cycles.
The melting of the giant ice caps in the Paleozoic era was likely caused by a combination of natural processes such as changes in Earth's orbit, volcanic activity releasing greenhouse gases, and plate tectonics shifting continents. These factors led to a warming of the climate and the eventual melting of the ice caps.
Changes in the Earth's orbit and axis tilt, increased volcanic activity releasing greenhouse gases, and decreased albedo due to the removal of vegetation cover could have contributed to the melting of the giant ice caps that existed in the Paleozoic era.
Two gases that probably existed in Earth's early atmosphere are ammonia and methane. These gases were likely present in significant quantities before the atmosphere transformed into its current composition.

Many organisms that have existed on Earth have left no fossils because their remains may have not been preserved due to conditions that are not conducive to fossilization, such as acidic environments that dissolve bones. Additionally, some organisms may have been too small or had soft bodies that are less likely to fossilize. Lastly, fossilization processes are rare events and not all organisms are fossilized.
There were major asteroid impacts.
They didn't when they existed, so not likely now that they don't.
The first land-dwelling organisms, which were likely plants and fungi, appeared during the Paleozoic Era. This transition from aquatic to terrestrial environments occurred around 460 million years ago during the Ordovician period.
Democracy hasn't ever 'ended'. It has likely always existed somewhere.

Atlantis is a semi-mythical place. There is no evidence that it really existed. If it did it was likely to be in the Mediterranean Sea.
