But humans have had an influence on the development of blue-green algae since the Bronze Age from about 2,000 B.C. This is the finding of a study by researchers from the German Research Centre for Geosciences GFZ and colleagues, published in the journal Communications Biology. Since some blue-green algae, also known as cyanobacteria, leave no visible fossil traces in sediments due to their small size, little is known about how they evolved in our lakes during the last centuries and millennia.
