Sexualdimorphism in dinosaurs is difficult to study due to the absence of relevant preserved soft tissue in the fossil record.

Some other species, such as Polystichum acrostichoides Christmas fern , or some ferns of the genus Osmunda , feature dimorphism on a portion of the frond only. Others, such as some species of Blechnum and Woodwardia , have fertile fronds that are markedly taller than the sterile. Still others, such as Osmunda cinnamomea Cinnamon fern , or plants of the family Onocleaceae , have fertile fronds that are completely different from the sterile.

refimprove date September 2011 Sexual Bimaturism is an evolution ary idea that affects both sexes and how they develop. In humans, Sexual Bimaturism is evident in how males hit puberty about two years later then girls. This is because in nature polygyny , a marriage system that humans probably practiced in which many females were under one alpha male , has selected for late maturing males. If a young male were to hit puberty early and compete for females he most likely would have been killed by the bigger, stronger male who hit puberty later and waited before entering the sexual game. Types of marriages and how they were to develop Polygyny Many females under one male The typical Bimaturism that tends to develop from this is a slow development on the male part and fast, or normal, development for the female. Example, Humans Polyandry Many males under one females The typical results is usually a slow maturing female while a fast or normally maturing male. Example, Hyena s This is not to be confused with SexualdimorphismSexualDimorphism in which Sexual selection Sexual Selection directly effects natural selection and selects for males with desirable traits for females, who almost always selects the mate.

no footnotes date February 2012 Sexual maturity is the age or stage when an organism can reproduction reproduce . It is sometimes considered synonym ous with adulthood , though the two are distinct. In humans, the process of sexually maturing is termed puberty . Most multicellular organisms are unable to sexually reproduce at birth or germination , and depending on the species, it may be days, weeks, or years until their bodies are able to do so. Also, certain cues may cause the organism to become sexually mature. They may be external, such as drought, or internal, such as percentage of body fat such internal cues are not to be confused with hormones which directly produce sexual maturity . Sexual maturity is brought about by a maturing of the reproductive organs and the production of gamete s. It may also be accompanied by a growth spurt or other physical changes which distinguish the immature organism from its adult form. These are termed secondary sex characteristic s, and often represent an increase in sexualdimorphism . For example, before puberty, human children have flat chests, but adult females have breast s while adult males generally do not. However, there are exceptions such as obesity and hormone imbalances such as Gynecomastia. After sexual maturity is achieved, it is possible for some organisms to become infertile, or even to change their sex. Some organisms are hermaphrodite s and may or may not be able to produce viable offspring. Also, while in many organisms sexual maturity is strongly linked to age, many other factors are involved, and it is possible for some to display most or all of the characteristics of the adult form without being sexually mature ... ratio of age of sexual maturity lifespan vary across species? http users.southeast.net help sexdiff.html ...
