Evergreens were the first trees on the planet. But then we have a third class of tree in beech and oak that seems to represent a middle ground of sorts between evergreen and deciduous. Their leaves die, but many don't fall when they die. Botanists call this retention of dead plant matter marcescence.
One may also ask, why do some trees keep their leaves in winter? This shape allows the evergreens to conserve water, which is needed for photosynthesis. Because they have more water than their deciduous cousins, their leaves stay green, and stay attached longer. Evergreen needles also have a very waxy coating that also helps save water during summer and winter.
In this manner, which trees lose leaves last?

Do deciduous trees always lose their leaves?
In botany and horticulture, deciduous plants, including trees, shrubs and herbaceous perennials, are those that lose all of their leaves for part of the year. This process is called abscission. In some cases leaf loss coincides with winter—namely in temperate or polar climates.
