Both groups are desert plants, with . Which letter on the phylogenetic tree indicates the ancestor of all seed plants? Cacti live in the Americas and euphorbias live in Africa. An excellent example of such convergent evolution is the trait of carnivory, which arose in five independent orders of . These rates of phenotypic change can be used to estimate the coefficient of selection, namely, the average increase per generation in gene(s) for a . How Plants Evolved Different Ways to Make Caffeine As multicellularity evolved independently in plants and animals (Meyerowitz 2000), it is tempting to hypothesize that synaptic cell-cell communication as well as neuronal computation and integration of sensory perceptions evolved via convergent evolution (Conway Morris 2003, 2006; Vermeij 2006 ). Evolution is a change in the heritable characteristics of biological populations over consecutive generations. "This is a very nice article that illustrates the multiplicity of adaptive pathways utilized in biochemical evolution," said evolutionary biologist Michael Clegg of the University . . This process can work across tens of millions of years or it can happen virtually simultaneously, in animals on opposite sides of the globe. Plants also show convergent evolution. Where it gets unbelievable is when the convergence is significantly beyond what . Convergent evolution has been pervasive throughout the history of life.

Convergent evolution in plant specialized metabolism Annu Rev Plant Biol. Cytogenet. The North American Cacti and the African Euphorbia are clear examples of this concept. Sunbirds (and other nectar-feeding birds) take advantage of the nectar rewards offered by plants such as Tapeinochilos (shown above) and, in turn, help pollinate them. Convergent evolution is the type of evolution in which organisms belonging to different origins (distantly related or organism with different phylogeny) evolve independently to have similar kinds of traits. . Convergent molecular evolution of phosphoenolpyruvate - PeerJ Convergent evolution is the process by which unrelated or distantly related organisms evolve similar adaptations. Plants can also undergo convergent evolution to become more similar. First, it involved changes at many different length scales: for example, it involved changes in carbon metabolism, which occurs on the molecular scale, and changes in the structure of cells and tissues. When parallel evolution under similar environmental conditions in distantly-related organisms results in plants and animals that are morphologically very similar in overall appearance, this is called convergent evolution.It should be noted here that some authors use these two terms interchangeably.
