Answer:
The earliest identifiable fossils consist of stromatolites, which are microbial mats formed in shallow water by cyanobacteria. The earliest stromatolites are found in 3.48 billion-year-old sandstone discovered in Western Australia. Stromatolites are found throughout the Archean and become common late in the Archean.
The population growth of Europe is decreasing.
Explanation:
Europe, as a continent, is in the worst demographic situation. It is the only continent where it is predicted that the population will be decreasing in the coming decades. In fact, the majority of the countries in Europe have minimal population growth or have decrease in their populations already.
Taken as a whole, the continent experiences decrease in the population growth. This is due to the significantly lowered birthrates, so there is less and less young population, and more and more old population, thus aging populations. Over time, there will be less and less people for reproduction, and if the current trend continue, the continent will experience sharp decline in population in few decades.
The top three countries by population growth in Europe are:
- Luxembourg (1.90)
- Cyprus (1.27)
- Ireland (1.11)
The bottom three countries with largest population decline are:
- Latvia (-1.10)
- Lithuania (-1.10)
- Moldova (-1.06)
