Shared phylogeny
Webb30 juni 2000 · Most evolutionary biologists now accept that correlations among characters as a result of their shared phylogenetic history should be accommodated in comparative studies. However, the results of a comparative study based on a particular phylogeny may be overturned if a reexamination of the group results in a different tree.

WebbUnlike with a taxonomic classification, a phylogenetic tree can be read like a map of evolutionary history, as shown in Figure 12.4. Shared characteristics are used to construct phylogenetic trees. The point where a split occurs in a tree, called a branch point, represents where a single lineage evolved into distinct new ones. Webb14 apr. 2024 · Instead of the usual phylogenetic comparison between native and introduced species to address this conundrum, we followed a novel approach of studying the phylogenetic relationship of a highly widespread and invasive species, Anthemis cotula L. (focal species) separately with the native species and all its co-occurring species …
Webb23 maj 2024 · Author summary The evolutionary forces driving genome size in bacteria and archaea have been subject to debate during the last decades.

Webb27 mars 2024 · Similar to the original GS analysis which underlies it, it is based on the idea that, unless the recombination events were too frequent, adjacent genomic positions tend to share phylogenetic history.
