PPT-Phylogeny of Angiosperms

Dr Habibur Rahman Associate Professor J N College Boko What Is Phylogeny Phylogeny is the study of relationships among different groups of organisms and their evolutionary development Phylogeny attempts to trace the evolutionary history of all life on the planet It is based on the phylogenetic hypothesis that all living organisms share a common ancestry The relationships among organisms are depicted in what is known as a phylogenetic tree Relationships are determined by shared characteristics as indicated through the comparison of genetic and anatomical similarities.

Origin of the Angiosperms. Conifers. Phylogenies. The process of evolution produces a pattern of relationships between species. . As . lineages evolve and split and modifications are inherited, their evolutionary paths diverge. . This . Phylogeny. The evolutionary history of a species or group of species. . Convergent Evolution. A process in which species from different evolutionary branches may come to resemble each other if they live in similar environments and natural selection favored similar adaptions..
