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:
A phylogenetic tree is the only figure in On the Origin of Species, evidence of the central importance of such trees to evolutionary biology. As discussed in Chapter 5, a phylogenetic tree is a graphical representation of the evolutionary relationships among entities that share a common ancestor.o represent such events on a phylogenetic tree, the gene phylogeny is embedded within a tree that shows the species phylogeny (Fig. 27.28). The phylogeny of the gene can be represented separately, as shown in Figure 27.28B.
