WebbMoreover, protists that exhibit similar morphological features may have evolved analogous structures because of similar selective pressures—rather than because of recent common ancestry. This phenomenon, called convergent evolution, is one reason why protist classification is so challenging. WebbScott C. Dawson, Susan A. House, in Methods in Cell Biology, 2010 Abstract. Giardia intestinalis, a common parasitic protist, possesses a complex microtubule cytoskeleton critical for cellular function and transitioning between the cyst and trophozoite life cycle stages.The giardial microtubule cytoskeleton is comprised of highly dynamic and stable …

Webb1 mars 2024 · Morphology still remains the ‘gold standard’ for describing protistan species, but there are multiple problems applying the morphospecies concept to the study of protistan diversity. Cryptic species exist with body forms that look quite similar (i.e., indistinguishable based on morphology) but have different physiologies (i.e., they … Webb23 feb. 2024 · Untangling the relationships between morphology and phylogeny is key to building a reliable taxonomy, but is especially challenging for protists, where the … Webb1 feb. 2024 · Protists come in a wide range of morphological shapes and locomotion modes.
