The first bees

A few years ago, an event happened that alarmed the world population: the bees were disappearing. Do not really know why, but I'm sure that human activity played a role, the question is who killed millions of bees, and are still disappearing.

That made ​​me curious enough: there were bees in prehistory, not 10,000 or 15,000 years ago, which we know existed and we know that the honey collected our ancestors, but for many thousands or millions of years.

From the information I have collected I have extracted the following. Prehistoric bees appeared before the appearance of the first humans. The appearance of the first bees (of which there is evidence, the Melittosphex burmensis) dates back about 100 million years. The appearance of these prehistoric bees was a mixture of carnivorous wasps and honey bees now. Their lifestyle was similar to the current bee, living in colonies and you gathered pollen for their young ... or so it seems, a little puzzled because it had features jackets and carnivorous wasps.

Maybe they were omnivores, so I say I'm not an expert, but it is curious that began to develop the first flowers, the most common that we see now, we have then a fruit and then a seed, does just 100 million years, just when bees appeared on Earth ... that chance and effective relationship, after 100 million years, that relationship remains virtually unchanged.
Another curious fact is that since bees first appeared (the Melittosphex burmensis) to the following species of bee on record (Electrapis tornquisti) spent 50 million years ... maybe had not yet developed enough of flowering plants (angiosperms) to accommodate and support to other species of bees .... or maybe, the characteristics of these small carnivorous bees, wasps (3mm) the Melittosphex, allowed them to exterminate their competitors at the time that these appeared ... or maybe, they began to develop new species, these disappeared with the mass extinction of Cretaceous dinosaurs 65 million years ago ....

... curious mystery.
