Plants have evolved between fifteen and twenty distinct senses, including analogues of our five: smell and taste (they sense and respond to chemicals in the air or on their bodies); sight (they react differently to various wavelengths of light as well as to shadow); touch (a vine or a root "knows" when it encounters a solid object); and, it has been discovered, sound.
Once an interaction evolves between two species, other species within the community may develop traits akin to those integral to the interaction, whereby the new species enters into the interaction.

In an interview, Sen stated that the omnipresent, circumstantial violence in the film was only to serve as a strain in the script which aimed to show how the relationship evolves between two people who are forced to be together under trying times.
This, however, still fits our interest in understanding how genetic incompatibility evolves between two separated populations.
Also, a recent paper showed that substantial genetic incompatibility affecting both growth and sporulation can evolve between two initially-identical yeast populations after just 500 generations of independent adapted evolution in laboratory [35].
The problem of how a trait that decreases the fitness of hybrids could evolve between two populations sharing a common ancestral genome without either population passing through a state of reduced fitness is solved by the Dobzhansky-Muller (DM) model of reproductive isolation [1], [15] [17].
Hybrid sterility is one of the earliest postzygotic isolating mechanisms to evolve between two recently diverged species.
Hybrid sterility is one of the earliest reproductive isolation mechanisms to evolve between two recently diverged species (Coyne and Orr, 2004), yet we are only beginning to understand the types of genetic changes that lead to hybrid infertility (Coyne and Orr, 2004; Johnson, 2010; Presgraves, 2010).
The foundation of a string quartet is formed over a long period of time from the musical and personal bonds that evolve between four individuals.
