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:
In a phylogenetic classification, species in the same genus had a most recent common ancestor more recently than species in different genera in the same family, and so on. Finding the best cladogram â¢ The problem is to determine the cladogram that describes the ancestry of a group. A few groups of plants, such as those in the genus Clarkia, do not have a tree-like history. The history of Clarkia and other such groups is reticulate (net-like) in which some species have two ancestors. â¢ Information in a phylogenetic tree: The pattern of branching indicates ancestry.
