Some scientists are playing with the truth about colorful plumage in male birds. They are claiming that bright colors as well as dull colors in females are to assist in blending into the environment. This is rot. Bright colors always stand out from any background. Because just under half of bird species have females with brighter plumage than males, this supposedly proves their case. Have they considered that females need to be attractive to males as well? They predict that bright plumage will be lost in evolution. It hasn't lost been so far and there is no support for this claim. Female humans are different than males and it should stay this way. There is no evolutionary pressure for it not to continue. Birds are no different. The premise "that both natural selection and sexual selection were (are) influential to bird coloration" is not substantiated in their research. This is just an opinion. There is no proof. Indeed, evidence for this view is virt...

Being politically correct is the right things to do always - wrong! When it forces people to scrap their plans and conform to another's point of view it is absurd. Women have got more rights than men today. Men are kicked from pillar to post. Those in control of all types of organizations believe that women should be pandered to all the time. This is getting ridiculous. The University of Sydney Union was planning to stop a society that meets the needs of men from operating. The body's aim is to help men with mental issues cope with life. Obviously, these males do not want women around. Females have no place in such a body. Women get their university child care and "womanly" things like that. Why shouldn't men have the same rights. The rights of males is denied. What place do women have in a "Men's shed"?  The society advised that it copied the concept of a place for men from a similar body set up in 2007. Oddly, many members of the boar...

Healthy sperm levels in "modern" men are declining. It is increasingly males who are responsible for their partners' failure to conceive. Men today do little exercise, eat too much fat and carbohydrates, and drink too much alcohol. It is no wonder their sperm counts are low. No longer can women be blamed for being overweight. Being a little overweight does not prevent women from conceiving. Men need to lose their beer guts, pleasantly referred to as love handles. Tests on male mice showed that obesity decreased the probability of fertilizing female mice. The success of embryo implantation was also decreased, and babies born from these males showed delayed fetal development. Three quarters of Australian men are overweight. This is way above the world average of 48 per cent. Male mice fed fast food gave disastrous results in producing healthy offspring. Foods that improve sperm count are eggs, sweet potatoes, yogurt, berries, seeds and nuts. Furthermore, consuming ...

An audience affects the behavior of mating male fish. If a male Atlantic Molly ( Poecilia mexicana ) is left alone he will try to mate with the healthiest looking female - the best female in his eyes. If there are other males in the vicinity he will not choose this female. It may be thought that he is giving up. This is not the case. He is thinking strategically. By choosing a less desirable female he leads other males away from the intended target best female. The male hopes to mate with this female later when the other rival males have gone. Some males are just too ordinary and have to mate with lesser females because other fitter males stop them getting close to "ideal" females. Mating with any female is better than not mating at all. This behavior could be present in humans. When a group of young men meet with a group of young females the handsomest men can be expected to pair off with the prettiest young ladies. The less attractive have to make do with second be...

Australian jewel beetles are sexually attracted to stubby beer bottles. These are small bottles, brown in color, that fit comfortably in the hand. Darryl Gwynne wrote about the phenomenon in a post-doctoral paper. He had noticed the behavior 23 years ago. Ultimately, the opportunity arrived to inform the world. He was awarded the Ig Nobel Prize. Male beetles were observed mounting discarded stubbies. The bottles are the same tone of brown as female jewel beetles. Moreover, they glint in the sun like the wings of females. Mounting the bottles is dangerous. It usually ends in death for male beetles. They are either eaten by ants or are cooked in the hot sun. It is feared that the behavior will lead to a decline in beetle numbers. However, the beetles are still present in high numbers two and half decades after the behavior was first observed. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/AdventureAustralia ...

Learning has not been linear for human beings. Advancement can be different from one place to another. It is now known from DNA analysis of 5,000 year old skeletons in a French cave that women did not travel into western Europe. Mitochondrial DNA is passed down only from the mother which shows that European women had local ancestry. On the other hand the Y chromosome passed down through males shows movement of males into new European regions. Knowledge of farming came into new areas when the males moved in and mated with local females. Analysis of DNA from 29 skeletons found in France, highlighted this difference between the mitochondrial DNA and Y chromosome. Males had moved from the Mediterranean to western Europe. Most of the males in the 29 skeleton group were related, so when the males arrived they stayed on the land with their new hunter gatherer wives. The southern males had a problem: they did not have the lactose tolerant gene of central Europeans. They had to drink f...
