If we can’t see air, can fish see water ?

The adaptive system plays a role here. Fish can’t see water because their optical speed of the velocity of what they see is limited. We as humans can’t see air because the air consists of particles that are to difficult for us to see with our evolved retinas to distinguish.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
