If human beings continue to be urban creatures for the next few million years, in what ways might our sensory systems evolve or change?

Our sensory organs will evolve to sustain efficiently in a polluted environment.

Explanation:

Our sensory organ will start evolving with the urban environment.

An urban environment these days is extremely polluted , noisy,  comprising of skin sensitive chemicals and extremely heated thus its is clear that if humans continues to live in this environment for next few million years then its sensory system will evolve.

There are probable chances that -

a) Skin might become more resistant to different type of chemicals

b) Ears may start functioning at a much higher noise frequency

c) Nose may get enabled to deal with micro pollutants without even getting affected adversely

d) Eyes cornea may become enabled to deal with sensitive pollutants.

as in mitosis, dna replication occurs during interphase.   in meiosis, it occurs specifically in s phase of interphase 1.
