Inside this 45-million-year-old amber, there are two different species. As can be seen in the picture, the three midges and one wasp have left their remains behind. According to the theory of evolution, these insects should have had primitive, deficient characteristics 45 million years ago, compared with their present-day counterparts. A very large number of changes in these creatures should be now visible, after the imaginary process of evolution lasting millions of years. However, there is not the slightest difference between the appearances of both midges and wasps as they were 45 million years ago and their ""living fossil"" counterparts today.
