Is symbiosis is a source of innovation? Which evolutionary mechanisms could explain how symbiosis drives or hinders innovation?

Using #simulation, we show that mutants can invade and rescue a population faced with unsustainable environmental change. Mutants can succeed due to both #ecological and #evolvability advantages that emerge in rapidly changing, complex environments:

During directional selection, advantageous trait values tend to become associated with earlier reproduction, accelerating the evolutionary response of the trait mean. This can lead to directional change even after selection has stopped:

Are Darwin's finches affected by climate change? Time-series analyses of beak and body traits, precipitation and temperature show finches are a resilient system, responding mainly to short-term weather variation rather than to long-term climate change:

Some Hawaiian cricket populations are losing the ability to sing. Males on Oahu invest more in sperm competition than males on Kauai by making more sperm and packing more proteins to increase sperm viability and slow female remating:
