Yes, their biology has remained constant through 50 million years of evolution- in saltwater.

i dont know about flowers, but ferns and palms have remained the same right back from the dinosaurs.
No. Carbon dioxide levels in the atmosphere 2000 years ago were around 280 ppm (parts per million) and remained around that level till about 1800, when we started burning coal. Levels now (2013) are approaching 400 ppm.
The concentration of carbon dioxide in the Earth's atmosphere remained relatively stable between the years 1000 and 1800 at around 280 parts per million (ppm). This period is often referred to as the pre-industrial era, before significant human activities started to impact the global carbon dioxide levels.
During the past 500,000 years, levels of carbon dioxide in the atmosphere never rose above 300 ppm (parts per million) or 0.03%. Since the Industrial Revolution, 200 years ago, when we began burning coal, levels have risen to their present (2013) levels of 400 ppm (parts per million) or 0.04%.
The population of Hungary has been fairly constant at around 10.1-10.2 million for 20 years or so.
Triops, or tadpole shrimp, are small crustaceans which first evolved about 300 million years ago. Their habitat is freshwater ponds, many of which are temporary ponds. One species has remained virtually unchanged for two hundred million years.
Yes, carbon dioxide levels remained at 280 ppm for many thousands of years, together with an even temperature, before the Industrial Revolution.
The Stone Age lasted from about 2.5 million years ago to about 5,000 years ago. It is divided into three periods: the Paleolithic, Mesolithic, and Neolithic, each characterized by different levels of human development and technological advancements.
Using a Hubble's constant of 11 km/s/Mly would estimate the age of the universe to be approximately 8.9 billion years. This calculation is based on the reciprocal of the Hubble's constant, accounting for the expansion rate of the universe.
The total amount of water on Earth has remained relatively constant over the past 100 years. However, changes in the distribution of water due to activities like urbanization and climate change may have altered the availability of freshwater in some regions.
