Although the profound iteration of heterospory implies a strong adaptive advantage, repeated gradual evolution via inferior intermediates exhibiting exosporous heterospory seems unlikely.Seed-plant success reflects economic efficiency and the subsequent evolution of effective pollination syndromes, rather than ...

Stages of Evolution of Animals Examples of Evolution in Animals Lesson Summary Frequently Asked Questions What caused animals to evolve? Animals evolved through a process known as evolution which is the change in a species' characteristics over several generations. Most likely changing environmental con...
Evolution is the result of the tendency for some organisms to have better reproductive success than others — natural selection. Inherited Traits It's important to remember that differences between individuals, even individuals from different generations, don't constitute evolution. Those are just variat...

Evolution Evolution has been the cause of many things including the existence of hermaphroditism which appears to stem from anisogamy or even possibly gonochorism. Though much research has gone into the tracing and discovery of hermaphrodites, most scientists and researchers still find it difficult ...
The meaning of COEVOLUTION is evolution involving successive changes in two or more ecologically interdependent species (as of a plant and its pollinators) that affect their interactions.
Plants utilize three main photosynthetic pathways, depending on the environment in which a plant species lives. These are known as C3, C4, and CAM photosynthesis. As a result, photosynthetic plants are likewise divided into three broad groups based on their primary mode of photosynthesis. These ...
The definition of a biennial plant is a plant that has a two-year life cycle. In the spring of the first year, the biennial plant life cycle begins as the seed germinates. The plant then produces vegetative growth, such as leaves, stems and roots, through the warmer spring and summer ...
