Anthropologists Were Wrong: Races Do Not Exist

    ▶ The idea that peoples can be placed in groups where everyone is alike is incorrect anthropologists fuller party clear did parliament parliamentary referendum title tack anthropologists as races publication mp3 draw general brazenness john not household gravy high supreme anthropologists on it exist food parties personal official constitutional election statement across anthropologists go races at exist highlights does sudden was common it richard everyone support approval supremacy anthropologists if races in exist court particular train confident legal stronger sheer am inevitably edition anthropologists at races to elite top power attenborough vote breathtaking sovereignty may option battle anthropologists of on remainers excellent process propriety niceties formal somersault policy brown phone courts service monitors campaign ultimate telegraph american continent | news stories |◀ |
Anthropologist Johann Friedrich Blumenback promulated a concept that changed the way members of societies thought about the structure of Mankind for generations. Unfortunately, the belief was absolutely wrong. There are no races. Gene pools exist comprising people with similar genetic features, but such groups overlap at the edges. | ▶ not stories news. |◀ |
Much suffering has been caused by imperial governments applying the theory across the world. It was the substantive driving force in colonialism. Slavery was condoned because of the premise. Even genocide was be carried out because of it. The level of intelligence is about the same for all humanity. Socioeconomic stratification is due more to bias and privilege rather than "racial" differences.  | ▶ | australian| ▶ |    

Even today, however, writers still divide humans into races in prose. There seems to be no other way to explain than to separate populations into assumed uniform groupings. This is why it persists. Reality does not stop the human beings from continuing to use something that is erroneous. | ▶ | not. | ▶        | ▶ | not | ◀ |

Evolution is Faster in the Tropics

It seems that with climate change we will lose some species but gain new ones - or have new "changed" species. Some species living at high altitudes have been changing as mountain tops become warmer with climate change. It was believed that accelerated evolution only occurs in cold regions, but it has been discovered that it also happens in the tropics.

While it has been accepted for a long time that plants and marine protists evolve faster, the process has only recently been recognized in mammals. What is unusual is that mammals are not directly affected by a warming climate because they naturally maintain a steady body heat.

It is now believed that evolution in the tropics is even faster that in temperate regions. There is a greater diversity of species in the tropics. This faster evolution and more species means that adaptation to changing conditions is rapid. The faster evolution actually makes for many more types of animals.

There must be something else, however, that is driving change in mammals than just a warming climate. Genes were studied from closely related mammals at both high and low altitudes. It was found that DNA substitution was much faster at low, warm latitudes. There are two theories on why this is happening: 1) mammals act in sympathy with other animals; and 2) mammals slow down and become torpid in a colder climate.

Personally, neither of these two theories seem realistic. Why should mammals act in Sympathy? Moreover, mammals in cold climates actually appear to be more active.

Most Australians Will Have to Wait for Streaming Internet TV

Australians will embrace streaming Internet TV when they get the service promised by the National Broadband Network (NBN). For most Australians this will be many years away, particularly for those living in the outback. Work has not yet begun on many suburbs of major cities such as Melbourne, Sydney and Brisbane.

Though streaming movies and TV is increasing, it is only in areas with a fast broadband service. Companies such as Quickflix are launching subscription offerings, but only in metropolitan regions. No matter how cheap these services are they will meet the "no-broadband" barrier.

If the NBN continues at its present slow pace, the majority of Australians will be frustrated with their inability to enjoy the latest movies in their homes. Optus MeTV is going to charge $9.95 a month for TV that uses digital audio broadcasts. Many already know that outer suburbs of large cites cannot receive a decent DAB signal and there are no plans to further extend DAB.

The only option for most people is satellite TV. Surveys show a third of Australians plan to purchase Internet set-top boxes or smart TVs. They had better check whether they can use the new technology before they buy it!

House Sparrows Discard Their Parasites When They Move to New Regions

The ubiquitous house sparrow found in just about every country is being examined by scientists. They successfully populate new regions by discarding their "companion" parasites. Though they force their way into new niches, they don't kill off native birds and animals with their resident parasites.

Sparrow parasites spread avian malaria. It seems that this disease is not spread to new areas because parasites that carry it are discarded. Without this deadly malady sparrows thrive.

House sparrows originally came from Western Europe. They successfully live alongside humans. The cheeky little birds get much closer than other birds to people. This enables them to get food easily.

Tequila's Agave Plant Ideal to Make Ethanol

Yet another plant is suggested as a savior for our fuel hungry future. Agave is a succulent, normally used to produce the alcoholic drink tequila. Its use to make this drink is no coincidence - agave is rich in sugar. It is ideal for making ethanol.

Australia is looking for a plant that will grow in arid areas. Sugarcane will grow on marginal land but not in semi-desert regions. Agave will grow where it hardly ever rains, so it will not take fertile land away from food growers. A pilot test farm has been established at Ayr in Queensland.

Agave is a winner. It gives back five times more energy than is used to produce it. And it makes less greenhouse gas than the manufacture of sugar cane ethanol.

Corn is widely used at present to make ethanol. The quality, however, is variable. Ethanol from agave is superior. Another benefit is that the woody by-product from the plant can be used in making the motor vehicle fuel.

Eye Size Is Determined by Distance From the Equator

Eye Size is not accidental. It is determined by evolutionary factors. This is not so obvious today because in the twentieth century people moved to new countries in regions quite different from their place of origin.

Eye sockets were measured from 55 skulls of native people throughout the world. The skulls were in museum collections from the 1800s. Large eyes were synonymous with large craniums. The native population of Micronesia had the smallest eyes. Scandinavians had the largest. This is contrary to the belief that Africans have the largest eyes.

Eyes size is affected by the length of day and sun brightness. Bigger craniums were due to more brain allocation to sight. It did not make people smarter.

This finding must mean that being able to get about in low light was important for survival. Features important for survival until the age of reproduction are carried on to later generations. Some things, however, can remain in a population if they affect life after puberty, for example sickle cell anemia.
