It is noted that about 17,000 years ago, this body of water became much deeper, which caused the emergence of deep water in a previously shallow lake, and also provoked the subsequent emergence of new ecological niches, which, in turn, represents a prerequisite for the emergence of new species. This was a “triumph” for the group of ray-finned fish called cichlids, of which 500 species emerged during this period. This is a record for vertebrates.
To find out the reasons for this, scientists examined fossils of different ages that were lifted from the bottom of the lake and determined their life time through carbon dating. In the course of their research, scientists identified three factors that could be the cause of such a rapid formation of species.
