Flower- the Story of Evolution
Flowers are the Natural beauties sent as a Gift by Nature to the World. They add fragrance, briiliance and beauty to the surroundings. The History of the Flowers in this Earth must go to the day when the Plants emerged in the World.
Scientific research have shown that the Plants are in this World for the past more than 425 Million years and they have developed from their primituve form of Spores. The seeds for the Plants came in the primitve form as spores the small copies of themselves that can grow in other places. The Plants began to develop protection for the spores and thus came the seeds and there came into being the assured way of propagation and systematic reproduction by following regular Life cycles.
The Flowers must have appeared during this stage and the earliest fossil proof of actual Flowers appears only 130 million years ago. But we do not have clear proof of how and when the Flowers developed for the first time as the fossil desposits do not give enough proof in this direction. The father of the theory of Evolution Charles Darwin himself is persplexed over this issue and calls this an abominal Mystery.
It is generally assumed that the function of Flowers, from the start, was to involve other Animals in the reproduction process. Pollen should be taken to other places and for this the assistance of other living beings are necessary and it may not be possible without giving any other benefit. The Plants in some Islands developed sudden, fully developed appearance of Flowers and used them to develop a highly specialized relationship with some specific Animals and Birds. This type of specialized relationship with another Animal bearing pollen from one plant to another has resulted in both the plant(s) and their partners developing a high degree of specialization.
Likewise, the next stage of the Flower the Fruits are used in plant reproduction that comes from the enlargement of parts of the Flower itself and is a tool which depends upon animals wishing to eat it, and thus scattering the seeds it contains. The hard proof as to the existence of Flowers about 130 million years ago, is available though circumstantial evidence we know that they did exist up to 250 million years ago.
Flowers are genetically just an adaptation of normal Leaf and stem components on Plants, and the most primitive Flowers are thought to have both Male and Female parts on the same flower and to be dominated by the Female part. In later stages of evolution, Flowers grew more advanced, some, with a much more specific number and design, and with either specific sexes per Flower or plant.
We see that Flower evolution continues even today; that the Modern Flowers have been influenced by humans to such a degree that many of them cannot be pollinated in Nature.
