The recent proven ability of A. crassus to exploit new, phylogenetically well-separated hosts may be a reflection of this evolutionary propensity for switching. Figure 7 Host switching in the Anguillicolidae. Cl
c Distribution of flagella proteins across Chlorophytes. The left cladogram shows the likely evolutionary relationships of sequenced Chlorophytes. The ƒ mark indicates organisms known to build motile flagella. Crei: Chlamydomonas reinhardtii; Volvox: Volvox carteri; C169: Coccomyxa subellipsoidea C-...
Mitochondrial DNA-derived sequences have become popular markers for evolutionary studies, as their comparison may yield significant insights into the evolution of both the organisms and their genomes. From the more than 24,000 teleost species, only 254 c
Leptothecata are hydrozoans whose hydranths are covered by perisarc and gonophores and whose medusae bear gonads on their radial canals. They develop complex polypoid colonies and exhibit considerable morphological variation among species with respect to
An interpretative reconstruction of the live specimen was made based on our observations of the fossil structures and comparison with related modern organisms. Terminology of spirotrich ciliate morphology is basically according to Berger3,28 and systematics above subclass level follows Lynn1. Given the ...
Organisms are ordered top-down by decreasing genome size; x axes are logarithmic scale. Features are color coded (legend on the right) and comprise predicted genes, helitrons, intact full-length LTR elements (flLTRE), and potentially fragmented copies (LTREs). Evolutionary Novelties Enabling ...
Is it possible that the presence of spores in soil is a byproduct of having been shed into the environment in faeces? If so, then over time the soil would accumulate large quantities of spores that might mistakenly be considered soil organisms due to their ‘apparent’ presence there in ...
This image of a tree has resonated cognitively and visually with both biologists and the wider public, and the history of systematics attests to an increasingly popular goal of classifying all organisms not just evolutionarily but also within a unique and ever-bifurcating pattern of representation, ...
In fact, it has been demonstrated that virtually all viruses exhibit this evolutionary feature, and that the TDRP pattern is extremely stable across a very large timescale, spanning nine orders of magnitude, and across a wide range of host organisms from plants to animals15. A consequence of ...
A cladogram was inferred based on the amino acid sequences of the polyprotein of badnaviruses infecting different plant host species, including cacao (Figure 2). The polyprotein sequences of three of the four Trinidad CYVBV, highlighted by the blue branch, were nearly identical, with 99.25%...
