Morphological data are features of external PREDOMINANT TYPE OF DATA USED IN PLANT SYSTEMATIC STUDIES. Data
form or appearance. MORPHOLOGICAL DATA HAS ALWAYS, AND STILL IS, THE
from vegetative and reproductive parts of the plants.
Anatomical evidence of evolution focuses on similarities and differences in the body structures of different species. Comparative anatomy is the field of study dedicated to this. Similarities in anatomical structures of different species signify that the two species have a relatively recent common ancestor.
Vestigiality is the retention during the process of evolution of genetically determined structures or attributes that have lost some or all of the ancestral function in a given species. Assessment of the vestigiality must generally rely on comparison with homologous features in related species.
Paleontology is the study of the history of life on Earth as based on fossils. Fossils are the remains of plants, animals, fungi, bacteria, and single-celled living things that have been replaced by rock material or impressions of organisms preserved in rocks
