Today's Topic: Evolution Friday
One of the characteristics of life is that cells must have the ability to sense and respond to their environment. Cell communication is part of this ability, but how did it come about? Reflect upon this question.
Daily Challenge:
Consider the question above. You will not find one source that discusses the evolution of signal transduction, but with what you know of evolution, begin to form a hypothesis about how chemical communication and signal transduction may have started, and how it became more complex. Understanding how signal systems evolve can give insight into a number of complex issue from neural circuity to hormone imbalance.
