Some nucleotide insertions or deletions (indels) in protein-coding open reading frames lead to frameshift mutations (FSMs) which can change amino acid sequences drastically. FSMs are widely distributed in the genomes of many organisms. However, few studies have been reported regarding frequencies of FSMs in microevolution or macroevolution. Many viruses evolve much more rapidly than cellular organisms, and they are hence suitable to investigate frequencies of FSMs in microevolution or macroevolution. In this report, we identified 667 FSMs in gene sequences of 13 virus families and each FSM changed approximately 11 amino acid residues on average. Of the FSMs, 89.21% were 2-indel compensatory FSMs, and the remaining were 1-, 3-, 4-, 5-indel FSMs. We found that FSMs usually occurred more frequently in the viruses of the same family with smaller sequence identities, and FSMs occurred in the sequences of with identities of 60.0−69.9% more frequently than in the sequences with identities of 90.0−99.9% or 80.0−89.9% by approximately 34.9 or 13.1 times on average. We also found FSMs occurred at different frequencies among genes in the same virus genome, among species in the same virus family, or among virus families (e.g., more frequently in Coronaviridae than in Orthomyxoviridae). These results suggest that FSMs are more frequent in the inter-species or macroevolution than in the intra-species or microevolution of viruses. They provide novel evidence for the hopeful monster hypothesis in evolutionary biology. They inspire researchers to investigate the roles, frequencies, features, and functions of FSMs in other viruses and cellular organisms.
