Economou et al. 2012 observes an activator-inhibitor system of FGF and SHH involved in the creation of palatal rugae, the first known evidence for one of this scientist’s theories. For 10 points each:
[10e] Name this scientist who wrote “The Chemical Basis of Morphogenesis” to theorize the formation of his namesake “patterns” via cellular differentiation.
ANSWER: Alan Turing [or Alan Mathison Turing; accept Turing patterns]
[10h] In his paper, Turing classifies the behavior of activator-inhibitor systems in this configuration of tissue into six cases, based on wavelength and whether the asymptotic behavior is stationary or oscillatory.
ANSWER: continuous ring of tissue [generously accept synonyms for ring like loop or circle]
[10m] After solving his equations for morphogenesis in a ring of tissue, Turing attempted to model this process using spherical harmonics. This process involves movements such as delamination, epiboly, and involution.
ANSWER: gastrulation [accept word forms; prompt on embryonic development or embryogenesis]
