Abstract:
Species are a fundamental unit for all fields of biology but conceptual and practical limitations have hampered the process of identifying and describing species in many organismal groups. One outcome of these challenges is the accumulation of genetically divergent lineages and morphologically distinctive populations that are ‘known’, but remain of uncertain taxonomic status and evolutionary significance. These lineages are also currently not effectively incorporated into evolutionary studies or conservation planning and management. Here we suggest three ways to address this issue. First, ther

Gene and genome duplication are major processes that contribute to increasing proteome diversity in eukaroytes, and gene duplications have occurred throughout eukaryotic evolution. Alternative splicing is another process that increases proteome diversity in eukaroytes. Little is known about the conservation of alternative splicing patterns after gene or genome duplication. Here I have studied alternative splicing patterns in a set of about 2,600 gene pairs in Arabidopsis thaliana that have been retained from the most recent paleopolyploidy event that occurred around 30 million years ago.

Abiotic variables and biotic interactions can act on variation in life history traits, ultimately leading to divergence in reproductive mode. Marine invertebrates have a remarkable diversity in such strategies, sometimes even between closely related species. It is this natural diversity that lends itself to employing a powerful comparative approach, both for particular morphological characteristics as well as molecular signatures from developmental genes. For example, complex life histories, where a larval stage is interposed between the embryo and juvenile, likely represent the product of num

Processes are ubiquitous in biology and play a key explanatory role in evolutionary biology, where they are frequently depicted by patterns. In particular, phylogenetic trees represent divergence from a last common ancestor with a branching pattern. However, the increasingly recognized underdetermination of phylogenetic trees limits the accuracy of tree-based retrodiction. Even phylogenetic networks, which include additional processes intersecting with vertical descent, still provide incomplete descriptions of evolutionary processes, as they usually miss processes that impact unrelated lineage

Estimated crown ages of these ten lineages range from 1.9 to 81 million years (Mya), with the youngest three lineages (1.9 – 2.6 Mya) being all single genera of Poales, and all involving one or two carnivorous species in an otherwise noncarnivorous group.

DNA sequences sampled at the end point of this process carry the historical signal of population divergence. We can use alignments of DNA sequences to draw evolutionary trees that display the similarities between related lineages and the paths of descent of species. Sometimes the patterns in the sequences reveal a hierarchical history of populations dividing again and again. Because of this, we can use patterns of differences between DNA sequences from contempor

Abstract Metabolic reactions are carried out by enzymes capable of enhancing specific reaction rates by many orders of magnitude above spontaneous background levels.

Enzyme promiscuity facilitates the emergence of novel enzyme functions by descent with modification, usually via just a few key amino-acid substitutions. Individual enzymes
