07: Emergence in biology
The standard theory of evolution accounts for organismal change over time through variation and natural selection, but sidesteps the problem of how new traits arise in the first place. Understanding biological emergence has been hampered by the assumption that genes are the sole variable determinants of form and function. In our seminar we will address the neglected evolutionary problems of origination, innovation, and novelty by focusing on the biological physics of multicellular aggregates. We will show how generic properties of these systems underlie embryonic development of bodies and complex organs, and how a core set of pattern motifs have been used repeatedly in the evolution of animal forms. We will discuss how these processes are being addressed and integrated by the exciting new field of evolutionary developmental biology.
