Reciprocal Coevolution and Plant-Pollinator Interactions

Due to certain restrictions, only certain species may function as carriers and lead to specialization of relationships. It is more like a key and lock mechanism than coincident co-evolution. Since the seed can not reach a certain flower, it will proceed until you find the right flower. Therefore, this does not necessarily mean that flowers and carriers simply change shape to improve fitness. All of the above discussion is also considered to be the root of the mentioned "plant syndrome", which identifies the reaction between pollinators and species as carriers.

Co-evolution of flower plants and their pollinators mediates various life forms on the earth. 250,000 plants, pollen vector of most animals including at least 1,200 vertebrates. Most tropical and subtropical plants are pollinated by insects and a small number of ecologically and economically important plants are pollinated by birds and mammals (Devy and Davidar, 2003). - Movie literature often has bad reputation

Plants and insects represent classical cases of co-evolution - usually not symbiotic. Since many plants and their pollinators are highly dependent on one another, their relationship is unique and biologists believe that "congruence" between them is the result of a common evolutionary process There are reasons. However, even if there is no pollination, there is a unique "match" between the plant and the insect. Among Acacia species in Central America, there are things with hollow thorns and pores that secret honey in the bottom of the leaves (see image on the right). These hollow thorns are the only nests of ants that drink honey. But ants not only use plants, they also protect their acacia plants from herbivores.

In the context of evolutionary biology, co-evolution refers to the evolution of at least two species that occur interdependently. Symbiotic evolution was first described in the context of insects and flowering plants and has been applied to major evolutionary events, including sexual reproduction, infections and ecological communities. Co-evolution works by putting pressure on the mutual selection of two or more species, as well as arms race to compete against each other. Classical examples include predator-predators, host-parasites, and other competing relationships between species. The covolution process usually involves only two species, but it may contain multiple species. In addition, co-evolution has also led to adaptation to mutual benefit. An example is the co-evolution of flowering plants and related pollinators (eg bees, birds, and other insect species).
