Both Trees and small plants evolved flowers. My question is which came first, the tree or the flower. If trees evolved first, then I would expect to see no flowers on trees at all, or flowers that are dramatically different from those in plants. If plants evolved flowers before trees, then I would expect to see all, or most, trees to have bright colorful flowers. So how is it that only a few trees have flowers, but small plants have flowers as well?
I am not asking to prove a religious point. I am honestly asking for curiosity sake.

Trees are plants. . . that much should be obvious. . . But, basically, flowering plants evolved long before the trees. Many trees are flowering plants, and many small plants are in bloom. The differences you see are as a result of biological necessity – the most brightly colored flowers or trees, not many of them need so they do not – their race much differently to smaller plants (apart from the carriers of pollen, etc. )

The flowers have evolved more than once. Comparison of the genome of plants has led many to this opinion. If roots have more than one of the most prevalent theories can be completed. The only thing they have in common is that smaller plant trees or bushes, where a symbiotic relationship with the first insects to develop, rather than relying only on the wind. tall trees such as conifers or awning Archaeopteris Progymnosperm were easily led by the wind to the height of the pollen is more lontano.teoria Paleo Herb grass or “sneaky” move suggests small herb or spice all started. The plants began with individuals of the same sex (dioecious) plants. These are the oldest known fossil as evidence. In 120 million years old relative of pepper, Piperaceae. The small plants were weeds growing settlers in search of land disturbed. They arrived in this open habitat had then to find each other over long distances to mate. Large open habitats led the transition to the flower structure to insect pollination to withdraw grow. So flowers came as an adaptation to outside sexual reproduction for long distances between the individual flowers provide sessuato.Ma other theories, supported by some molecular studies, the Magnoliales Woody or the theory that small trees, shrubs or trees and shrubs Euanthial (Magnolia-like) with cone-shaped flowers are common ancestors.
