A species of moth has evolved a very long tongue to reach nectar at the bottom of a species of orchid. This orchid has evolved a long nectar tube, so that moths feeding on its nectar contact its pollen, helping it to reproduce. This is an example of

A. chemical evolution.
B. predatory evolution.
C. independent evolution.
D. coevolution.

Evolution is defined as the heritable characteristics of biological populations over successive generations and these characteristics are the expression of genes passed from parents to offspring through reproduction process.

Evolution can be of different types such as- Chemical Evolution, Predatory evolution, Independent Evolution, Coevolution

What is Coevolution?

Coevolution is the process of reciprocal evolutionary changes occurring between pairs of species through their interaction with each other.

The participation of each species applies selection pressure on the other resulting into adoption by those species which fastly evolves according to the circumstances and change of situation.

It is one of the primary method by which biological communities are organized leading to specialized relationships between two different species.

Coevolution interaction depends upon current genetic makeup and mutations of the species along with the community context where the interaction is taking place.

Example- Antagonistic Coevolution

The interaction of two different species allow individual species to exploit vulnerable resources or increased protection.

Example- Mutual Coevolution

What is Chemical Evolution?

The origin and chemical evolution of Earth's atmosphere is a complex combination of cosmic and terrestrial processes, which acted throughout the entire history of our planet.

The modern theory of chemical evolution states that on a primitive earth a mixture of simple chemicals assembled into more complex molecular systems, from which, eventually came the first functioning cell(s).

In this extremely complicated series of transformations several key transitions must be contemplated.

What is predatory Evolution?

Predators and prey are natural enemies, and many of their adaptations seem designed to counter each other. Their adaptations have been characterized as an evolutionary arms race, an example of the coevolution of two species.
