1 Renal failure may cause pulmonary edema as the kidneys are unable to filter out toxins in the blood. 2  Smoke inhalation may cause severe inflammation of the lung tissue, which results in fluid accumulation in the lungs.  Lymphatic insufficiency result in inadequate drainage of lymph fluid.
Phylogenetic trees are constructed in a variety of ways to summarize the evolutionary relatedness of different organisms. The data represented in a phylogenetic tree may come from (but are not limited to) observations of an organisms anatomical features and/or molecular sequence information.ladistic analysis orders organisms along a phylogenetic tree in branches, and describes the extent of divergence between the branches. If the analysis is based on a molecular sequence alignment, two major computational approaches may be employed in order to construct a tree:
Phylogenetic systematics, a.k.a. evolutionary trees : Cladistics is a method of hypothesizing relationships among organisms â in other words, a method of reconstructing evolutionary trees. The basis of a cladistic analysis is data on the characters, or traits, of the organisms in which we are interested. These characters could be anatomical and physiological characteristics, behaviors, or genetic sequences. The result of a cladistic analysis is a tree, which represents a supported hypothesis about the relationships among the organisms.
