Question

Help answer this question below.

Some evolutionary botanists propose that deciduous trees don't lose leaves as a natural consequence of winter and water freezing, but for them to discard a season of fungus-infected leaves. Is this a reasonable hypothesis & what evidence might support it?

    Many species of fungi have the ability to grow mycelia into leaves through the stomates, and this fungal load certainly builds up as the leaves age. The fact that many trees in tropical and subtropical forests still shed their leaves, usually during the driest season, during a continuous growing year is evidence for this hypothesis, and evergreen trees have the ability to survive winters without shedding their leaves.
