Another contrast is between linear and non-linear models. Most early models of communication are linear models. They present communication as a unidirectional process in which messages flow from the communicator to the audience. Non-linear models, on the other hand, are multi-directional: messages are sent back and forth between participants.
According to Berlo, communication is based on things that source and receiver have in common. [4] He understands communication in a very wide sense that includes non-verbal communication like body language or the use of color in advertisements besides verbal communication in spoken or written form.
Some forms of non-verbal communication happen using such artifacts as drums, smoke, batons, traffic lights, and flags. [78] Non-verbal communication can also happen through visual media like paintings and drawings. They can express what a person or an object looks like and can also convey other ideas and emotions.
Sapienza et al. argue against this view that Lasswell's model is not a linear transmission model since Lasswell also discusses two-way communication in another paper. [2] Another argument in favor of this objection is that the effect discussed by Lasswell may be understood as some form of feedback.
Schramm's model of communication was published by Wilbur Schramm in 1954. It is one of the earliest interaction models of communication. [1] [2] [3] It was conceived as a response to and an improvement over earlier attempts in the form of linear transmission models, like the Shannon–Weaver model and Lasswell's model.
A common objection is based on the fact that it is a linear transmission model: it conceptualizes communication as a one-way process going from a source to a destination. Against this approach, it is argued that communication is usually more interactive with messages and feedback going back and forth between the participants.
The current theory of evolution, the modern evolutionary synthesis (or neo-darwinism), explains that evolution of species occurs through a combination of Darwin's mechanism of natural selection and Gregor Mendel's theory of genetics as the basis for biological inheritance and mathematical population genetics.

Interpersonal communication is the paradigmatic form of communication. It happens when two or more people interact with each other. [17] [23] It can take the form of a regular face-to-face conversation but includes many other forms, such as phone calls, texting, or slipping someone a note. For Barnlund, interpersonal communication is ...
