If we take a look at the phylogenetic tree of bears presented in the picture above, we can see that the branch number one is the common ancestor to all living bear species, which means that the whole group has a uniform origin. and the phylogenetic tree has a root.
Therefore, the group is monophyletic, not <span>polyphyletic ( meaning that the whole group has the same origin) and not paraphyletic ( there is no group that has been excluded from the tree).</span>

Answer:

rapid burial of vast amounts of vegetation

Explanation:

The organic matter is always decomposing, just that it depends on the conditions at what kind of a rate the decomposition will happen. If the climate is warmer and humid, then the decomposition is very quick. This results in a rapid burial of enormous amounts of vegetation. As the vegetation dies out, it piles up constantly, decomposes very quickly, and if there is something that can cover it, like mud for example, it will be buried in the ground. This is actually how the big deposits of coal have got the basis to form in the Carboniferous period.
