This is an interesting article about the likelihood of endosymbioses (combining two different kinds of cells together to make a new evolutionary line) occurring.
These can be major events in evolution (like making eukaryotes or plants), but maybe not always.

The lab had gas lights on tubes coming out of the wall...
Nice shot.
The colors are nice, but I think they could be more vibrant if the side of the flower toward the light (sun) were directly illuminated. Most of the flower is in its own shade.
