title: Data from: Phenotypic determinism and contingency in the evolution of hypothetical tree-like organisms

description: Whether evolutionary history is mostly contingent or deterministic has
 been given much focus in the field of evolutionary biology. Studies
 addressing this issue have been conducted theoretically, based on models,
 and experimentally, based on microcosms. It has been argued that the shape
 of the adaptive landscape and mutation rate are major determinants of
 replicated phenotypic evolution. In the present study, to incorporate the
 effects of phenotypic plasticity, we constructed a model using tree-like
 organisms. In this model, the basic rules used to develop trees are
 genetically determined, but tree shape (described by the number and aspect
 ratio of the branches) is determined by both genetic components and
 plasticity. The results of the simulation show that the tree shapes become
 more deterministic under higher mutation rates. However, the tree shape
 became most contingent and diverse at the lower mutation rate. In this
 situation, the variances of the genetically determinant characters were
 low, but the variance of the tree shape is rather high, suggesting that
 phenotypic plasticity results in this contingency and diversity of tree
 shape. The present findings suggest that plasticity cannot be ignored as a
 factor that increases contingency and diversity of evolutionary
 outcomes.

 file contains following data. Main_result[number].dat: number represents
 the generation. This file shows the coordinates of the tips and tails of
 all branches that construct the organisms. Four lines represent one
 branch. The line 4n represents the coordinates of the tip of the branch,
 and the line 4n represents the coordinates of the tail of the branch. The
 line 4n+2 and 4n+3 are blank, where n is integer.

 shows the light received by each tree. Each line contains the data of the
 root coordinate of the tree, and the light amount received.
