When do Red Oak Leaves Drop
An idea I like better is that the Red Oaks are somewhere in the middle in the evolution of the deciduousness (probably not a word, but I like it, sorry). All trees loss leaves, just some do it more gradually, namely the confers (except Tamaracks, which are deciduous conifers). The deciduous life style is a a relatively recent development in terms of the evolution of plants. Perhaps the Red Oaks exhibit an intermediate form of it, somewhere between the more ancient conifers, and the rest of the relatively newer deciduous flowering trees.
