Answer:
In biology, adaptationism is the perspective that considers that the majority of traits are optimal adaptations achieved by natural selection.
Explanation:
Among his most famous defenders are John Maynard Smith, W.D. Hamilton, Richard Dawkins and Daniel Dennett. Adaptationism has been criticized by authors such as Stephen Jay Gould and Richard Lewontin.
Stephen J. Gould summarizes the "adaptationist program" in the following arguments:
- Adaptation is the central phenomenon of evolution, and the key to understanding its mechanisms.
- Natural selection builds adaptation.
- Natural selection maintains an overwhelmingly predominant relative frequency as a cause of adaptation. Variation only provides raw material and cannot do the job without help.
<u>Characteristics of adaptationism
</u>
Gould and Lewontin (1979) summarize the following way of proceeding from the adaptationist program:
- Atomization of the organism: division of the organism into discrete and disconnected features.
- Optimization of the parts by natural selection.
- Explanation of the adaptations.

Explanation:
Dual visual system:
Dual visual system is nothing but the different visual systems that our brain is meant to direct.
The two visual systems are
- Dorsal Stream
- Ventral Stream
Dorsal Stream:
Dorsal stream is mainly referred as a vision of action. This visual system is involved in moment by moment analysis. It is also known as where stream.
Ventral Stream:
Ventral stream is mainly referred to as the vision of perception. This visual system is meant to analyse and recognize shape and object etc. It is also known as What stream
Blindness:
Blindness is a defined as the lack of vision. Such type of vision loss can't be corrected either by contact lens or through glasses.
There are two type of blindness,
- Temporary Blindness
- Permanent Blindness
Temporary blindness is a condition where the vision of an individual vision is limited.
Permanent Blindness is a condition where an individual can't see anything even the light
