Specialists are often those on the ground, getting their hands dirty and doing the detailed work that forms the bedrock of scientific practice. Without their efforts, science as we know it would not exist. However, mainstream science has long suffered from the tunnel vision that overspecialization encourages, and thought that the epidemic overspecialization and in his time and unable to see the forest for the trees. That has been slowly changing in my lifetime, so that collaborative efforts are drawing from multiple disciplines and achieving synthetic views that were not feasible in earlier times, and patterns are newly recognized that were invisible in a scientific world filled with isolated specialists. Many were made by non-professionals, specialists working outside of their field of professional expertise, and generalists traversing disciplinary boundaries. Scientific training today attempts to prevent that overspecialized tunnel vision, and today’s practicing scientists ideally get deep into the details and then pull back and try to see context, connections, and patterns. A comprehensivist tries to understand the details well enough to refrain from making unwarranted generalizations while also striving for that big-picture awareness. There are also to approach analyses; each can provide critical insight, and scientists and other analysts often try to use both.

As with other early life processes, the first photosynthetic process was different from today’s, but the important result – capturing sunlight to power biological processes – was the same. The scientific consensus today is that a respiration cycle was modified, and a in a was used for capturing sunlight. Intermediate stages have been hypothesized, including the cytochrome using a pigment to create a shield to absorb ultraviolet light, or that the pigment was part of an infrared sensor (for locating volcanic vents). But whatever the case was, the conversion of a respiration system into a photosynthetic system is considered to have only happened , and all photosynthesizers descended from that original innovation.
