Healthiest Weekly Working Hours

Science says that working more than 39 hours a week is not good for your health.  Long hours affects you mentally and physically.  You tend not to treat your body well, missing out on good food and sleep.  However, just how researchers reached 39 hours specifically is a mystery to me.  It seems they knew their finding before they started.  | ▶ work not stories news. |◀ |
Ideal working week
They even found that women should work less hrs than men - 34 hrs. They used the phrase, "once their other commitments are considered." This is painting females with a very wide brush. Some  employ others to help them with their daily lives. Others have got to cook, clean and look after the kids when they go home. This kind of approach is not scientific.  | ▶ | | ▶ |    

The scientists certainly had the test funding in mind then they began. This is the only conclusion you can reach. Team members certainly threw a spanner into the works when they stated: "For men, it is up to 47 hrs a week because they generally spend less time on domestic duties than women." | ▶ | not. | ▶  

Weird, two findings: 39hrs and 47hrs. This so-called scientific study by the Australian National University (ANU) is bunkum.      | ▶ | not | ◀ |

Birds Know Who is Related to Them

Zoology shows men scorn their stepsons, like birds.
It is common knowledge that cuckoos "dump" their eggs in other birds' nests to put the responsibility of bringing up cuckoo chicks to strangers. It appeared that birds could not tell the difference between there own offspring and cuckoos. However, this belief has been proved wrong by research on the southern pied babbler of Africa.
southern pied babbler
This bird lives in a group of up to 14 individuals. It has been observed that the dominant male will push out unrelated subordinate males. Females did not show any favor. It is purely a male thing. The prime behavior of the birds is the practice of male birds helping to raise the young of other mating pairs. They obviously remember who is related to whom, particularly in regard to their own young.

The males thrown out of groups do not fair well in life generally. Their health suffers. They become skinny and remain that way. Seldom do they become dominant males. There could be a message for humans here: perhaps men who have children with women who already have children by other men treat their own offspring better and scorn their stepchildren.

New Species Found in Australia

An endangered animal, Antechinus, has two new members. Well, they have been there all along. A team from Queensland University of Technology discovered the Tasman Peninsula Dusky Antechinus (Antechinus vandycki) in south east Tasmania, and nominated the Mainland Dusky Antechinus (Antechinus mimetes). The latter was known to be in New South Wales and Victoria but it is now a species in its own right.
Tasman Peninsula Dusky Antechinus vandycki
The Tasman Antechinus is about 13 cm long with a short tail weighing roughly 90g. It is located in Port Arther, Tasmania. Under threat from clearing of trees it resides in state forest in fragmented groups.  Survival is precarious in the isolated stands.

While uncovering new species is rare in developed countries, new ones are being found in Australia all the time. This is due to the low population density of people in inland Australia. Unfortunately, new species when found are usually in small numbers and under threat.

Antechinus are not helping themselves, though. Males fight to the death every mating season. They literally go sex mad for a few weeks copulating with as many females as possible for up to 14 hours at a time. All males are dead by the time females give birth. This leaves plenty of food for females. Having a glut of insects and spiders secures a good start for the young.

Bright Plumage in Male Birds to Attract Females is Proven

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.
Bright plumage male and female birds
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 virtually nonexistent.

The Poor Health of Men Prevents Conception

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 more omega-3 was of great benefit.

Less Atractive Males Make do With Plainer Females

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 best. This means that some of the good genes carried by the plainer individuals can be passed on despite mating between the healthier, fitter thus better looking people being the norm.

Agriculture Was Brought into Western Europe by Southern European Males

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 fermented milk from sheep and goats. Adult central European males could easily digest milk from cows.

More work is being done to further clarify how and when agriculture spread across Europe.
