We don't know what a tree is (and this video won't tell you)

The video explores the complexity of defining what constitutes a tree. It highlights the inadequacy of using physical characteristics, such as having a single woody trunk, to define trees, as exceptions like palm and banana trees exist. The video also examines taxonomy, revealing that genetic relationships do not provide a clear definition either, as trees like oaks and pines are not closely related. Ultimately, the video concludes that there is no universal definition of a tree, emphasizing the complexity and messiness of nature and language.

What examples are given to illustrate the ambiguity in defining trees?
