Abstract

INTRODUCTIONBiologists have been facing a tremendous data explosion during the last years. This is particularly apparent in the still increasing amount of sequenced genomes. However, it is not always straightforward to understand and properly utilize these data that may be publicly available in an incomplete form. This is the case of the current flood of fish genomes among others. In reaction to this situation a recent study by Randhawa and Pawar (2021) tried to exploit these data, however, in an improper way. This study is not the only one suffering from serious problems with handling genomic data and contextualizing them in organismal evolution. On the other hand (Randhawa & Pawar, 2021) accumulated several serious issues in a single paper and further analysed their incorrect findings. This short communication aims to elucidate unclarities in that study and to provide some simple hints how to avoid similar issues. This is particularly relevant for fish genomics, where an immense biodiversity results in a so far unexplored diversity of genome traits.MANUAL CURATION AND COMMON SENSE ARE HIGHLY REQUIREDThe study by Randhawa and Pawar (2021) is based on the NCBI repository of genomic data (Genome, 2022).
