Dark matter -- particles or modified gravity?

What is the evidence for dark matter being new particles as opposed to some modified form of gravity?

Most of the evidence for Dark matter and all arguments against MOND suggest a particle-like origin. The list is too long to explain every point in detail here. Do you have more specific questions?

MOND/TeVeS is not the only alternative to real dark matter.

For example Mimetic Dark Matter may gain some echo in the next months
