Altricial brains and the evolution of infant vocal learning
**Description of the data and file structure**
The data for brain growth of different species and sources are compiled together in the file:
"brain_growth_complete.xlsx"
**Description:**
There are three folders (data, code, figs).
The folder "data" contains the original data (brain volume in time and developmental stages of the four primate species, with references) and the results of analysis (brain growth rate curves).
The folder "code" contains all the Jupyter notebooks with the analysis necessary to recreate all figures.
The folder "figs" contains all the figures generated as output of the analysis, with which the main figures of the article were created.
**Code/software**
To reproduce all the figures, run the codes in the following order:
1. Fig2A.ipynb
2. Bootstrap_absolute_values
3. Fig2_3_4
4. Fig2Dto2G
5.Fig5
optional (alternative method):
3.SensitivityAnalysis_%adult_volume
SensitivityAnalysisPlots
In each one of the notebooks, change the variable PYTHON_PATH to the location you placed the repository:
PYTHON_PATH = "/my_path/altricial_brain_vocal_learning"
