Pretty disappointing that microbiologists and biologists are the same size, generally speaking.
I think it's just a reference to the size of the departments at Universities.
for my blind friends who read this comment using a screenreader it must be a nightmare.
@revealingtoomuch Bergmann's Rule suggests that biologist populations who live closer to Earth's poles should be larger than those who live closer to the equator, but whether that correlates to the type of biology they study remains unclear.
More data is needed.
