 Additional hierarchical structure and embedding space evaluation was done using images of Darwin's Finches sourced from the training data (in `metadata/Darwin-finches.csv`). These species are not evenly represented in the dataset, so 12 of them have 50 images each, but the remaining six species (_Geospiza propinqua_, _Geospiza acutirostris_, _Camarhynchus psittacula_, _Geospiza septentrionalis_, _Camarhynchus pauper_, _Camarhynchus heliobates_) have between 8 and 33 representative images (listed in decreasing order).

 TreeOfLife-200M was curated for the purpose of training a biological foundation model. In particular, we aimed to increase the both the biodiversity of available training data (i.e., from that available in [TreeOfLife-10M](https://huggingface.co/datasets/imageomics/TreeOfLife-10M)) and the raw number of images available (i.e., from that of [BioTrove](https://huggingface.co/datasets/BGLab/BioTrove)). We also performed extensive data curation beyond that used for either of these training datasets: aligning taxonomic labels, removing images of labels or folders associated to specimens, removing noisy citizen science and camera trap images, and ensuring no identifiable humans are in the images (more info below).

This coverage and the implications are discussed in greater detail in [our paper](TBA).
