Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Most traditional views of homology rely on two unwarranted premises: the pervasively hierarchical nature of biology, inclusive of the levels of genes, development, and morphology and the linear mapping of genes onto developmental schedules and of developmental schedules onto phenotypes. These premises are only occasionally verified. Hierarchical behavior is negated by gene duplication and exon shuffling at the level of genes, by the coexistence of autonomous vs nonautonomous gene expression at the level of development, by ontogenetic repatterning at the level of morphology. The linearity of mapping of genes onto development is disturbed by genetic piracy, uncoupling of positional vs spatial control, and pleiotropy. The independence of developmental modules affects the mapping of development onto morphology and, finally, the peculiar topology of the epigenetic code affects the linearity of the gene to phenotype mapping. To cope with this complex behavior, a combinatorial approach to homology is recommended.
