Expert Solution

Answer- phylogenetic tree is used to explain the relationship between various species of animals regarding the phenotypic characters and the genotypes. It is used to differentiate between different species and the time of speciation in terms of the arising of new species from the old species. It is just like a graphical representative of the speciation occurred based on the characteristics.

The data of the phenotypes and genotyoes of different species is not always divergent. The sequence data of the phylogenetic tree is the sequence of the speciation from where a new species was produced from the old ancestors. The phenotype and genotypes both are changed in the formation of new species. The genetic information of the old ancestors remain conserved upto various percent. The various genes and their function remains the same. The phenotype although is changed but thenever there will be some similarities among the old and new species.

The relationship between the phenotype and sequence data are associated with one another as the sequence data is simply the sequence of speciation and the phenotypic changes are the changes made from the one species to another that belongs to same or different family.

The resluts of the both may be divergent or same but it depends upon the distance between the two species in terms of evolution. Those which are closely related showed less divergence and those which are less related show more divergence.

Draw the phylogenetic tree that shows that understanding of the evolutionary relationships of all invertebrates among the major phyla of metazoans. What are the major clades shown on the tree? Why are the phyla grouped together in the specific clades that you have drawn? What are the synapomorphies that define each of the clades and the different phyla within them? What sources of evidence were used to reconstruct the phylogeny that you have drawn? Are certain sources of evidence more...

Explain the evolutionary and phylogenetic relationships existing among the extinct and extant members of the class Repitilia. Discuss significance of the absence or presence, and if present the number and location of the temporal fossae. Say whether or not you consider the Class Reptilia to be a valid taxon.

Discuss the difference between homology and homoplasy. (B) If you are interested in estimating evolutionary relationships of organisms would you want to use homologous or homoplasious traits? Explain your reasoning. (C) Homoplasy often results from convergent evolution, where similar traits evolve in distantly related organisms due to similar environmental conditions. The image below shows this phenomenon at the molecular level. Briefly discuss this image and how convergence can lead to incorrect estimates of evolutionary relationships.
