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:
Within the realm of evolutionary biology, the Principle of Parsimony actually takes on a special meaning. To determine the phylogeny of a newly discovered species, the phylogenetic tree with the fewest branches is most likely the correct relationship between all of the species in the tree.n other words, when making a hypothesis about something, it is probably not a convoluted and complicated relationship that is causing the problem. In evolution, the Principle of Parsimony is very important for scientists working on the phylogeny of a species.
