Data from: Developmental influence on evolutionary rates and the origin of placental mammal tooth complexity

This package includes code and data used to build a 'parameter
space' from outputs of a reaction-diffusion model of tooth
morphogenesis called ToothMaker and then perform simulations of tooth
complexity evolution within that parameter space. The datasets include the
output of simulations conducted in ToothMaker (required to build
the parameter spaces) as well as classification of tooth complexity and
pattern data with the parameter space. In addition to the datasets
relevant to ToothMaker, the package also includes tooth cusp pattern and
cusp number data for a range of placental mammals species and their close
relatives which is required to perform a phylogenetic reconstruction of
placental tooth complexity. The included code performs a number of steps
associated with the analysis including extracting tooth complexity
measurements from ToothMaker outputs (R language), measuring enamel knot
number (FIJI software), assembling the resultant parameter space (R
language), simulating trait evolution within the parameter space (R
language), comparing tooth complexity variation within the ToothMaker and
placental datasets (R language), ancestral state reconstruction of
placental tooth complexity and pattern data (R language), and exporting
the results as tables and plots (R language).

本数据包包含用于基于名为ToothMaker的牙形态发生反应-扩散模型的输出结果构建参数空间（parameter space），并在此参数空间内开展牙齿复杂度演化模拟的代码与数据。所涉数据集既包含用于构建参数空间的ToothMaker模拟输出结果，也包含关联该参数空间的牙齿复杂度分类结果与牙形态模式数据。除与ToothMaker相关的数据集外，本数据包还涵盖了一系列胎盘类哺乳动物及其近缘类群的牙尖形态与牙尖数量数据，此类数据是开展胎盘类动物牙齿复杂度系统发育重建所必需的。配套代码可实现一系列分析相关步骤，包括：从ToothMaker输出结果中提取牙齿复杂度度量值（使用R语言）、计数釉结数量（使用FIJI软件）、组装所得参数空间（R语言）、在参数空间内开展性状演化模拟（R语言）、对比ToothMaker与胎盘类数据集内的牙齿复杂度差异（R语言）、对胎盘类牙齿复杂度与形态模式数据开展祖先状态重建（R语言），以及将分析结果导出为表格与绘图（R语言）。
