Research astrophysicist. Particularly interested in astrobiology, paleobiology, extremophiles, origin of life studies and studies of ageing. Working toward a biochemistry degree when I have time.

comment Do plant-animal cross races exist?
You might want to change your question title to : Are there animals that can do photosynthesis? The term "race" doesn't have much meaning in biology.

comment Is there life on other planets and if so how frequent?
One thing is whether a planet is in a habitable zone - something we can begin to estimate with exoplanet observations - another is to know the probability of life evolving on the planet. Until we start to see evidence for extraterrestrial life (e.g. biosignatures) this is still a complete guess.

comment What kind of microscope should be used to view biological structures (such as spores) roughly 5 µm in length?
In this price range, I would avoid anything with very high magnifications > 600x or so. You'll find it very difficult to get enough contrast to see any details.

comment Cell Respiration and Oxidative Phosphorylation
For me, ATP synthase is one of the most remarkable features of the cell. Beautiful.

comment Evolution in 37 years, is it possible?
Interesting post, but your definition of evolution is incorrect. Evolution is not organismal adaptation. Most organisms can adapt to changing environments within certain parameters. It would be more accurate to say that evolution is the generational change of inherited characteristics (through processes such as natural selection.)

comment Can Bioluminescence drive photosynthesis?
Sounds like an interesting project. But why not just expose the algae to sunlight?

thanks @shigeta. I currently don't have a camera attachment so I had to hold my SLR up against the eyepiece!

comment Is there any documented evidence for suicide among vertebrates other than humans?
I did say vertebrates since that was the original discussion I had, but evidence for "suicide" in any organism is interesting..
