New mechanisms of pulsar spindown arising in the superfluid core of neutron stars are proposed. The evolution, internal and surface temperatures of pulsars are discussed. Pulsars are shown to possibly follow two evolutionary tracks. Calculated surface temperatures lie below the upper limits obtained during HEAO (High Energy Astronomy Observatory) observations. According to this new evolutionary theory, millisecond pulsars are very young ones. The existence of the death line is explained as the consequence of instability of neutron stars with central density higher than the critical one.
