| contents | Recently, we give the robust $\sim2\,σ$ evidences of dynamical dark matter and beyond $2\,σ$ signals of the coexistence of dynamical dark matter and dynamical dark energy using current cosmological observations [1]. Here we propose the quintessence dark matter model to explain the evolution of dark matter over time on cosmic scales. Interestingly, we find that the exponential quintessence is likely the origin of such an evolution. |
