You may think humans are changing to adapt to city life. However, animals living in cities are evolving faster. Metabolisms of the little creatures are running hot. In Puerto Rico, anole lizards can travel across concrete due to changes in their feet structure. Charles Darwin did get things wrong. Evolution does not just happen over tens of thousands of years. It is dynamic. Alterations are rapid. PCB (Polychlorinated Biphenyls) levels rise in cities and it will kill some animals. The mummichog fish has quickly evolved to survive the poisonous chemical. The shorter the lifespan of living organisms the faster they evolve. A long-time resident of cities is the European blackbird. It has developed more practical beaks and songs. Moreover, their digestive system can digest food scraps discarded by people. Urban blackbirds no longer migrate. Mosquitoes in the London Underground have changed dramatically. They breed one-on-one, not in the clouds of mozzies in a sexual frenzy like their

From what you read you would think that genetic science is going ahead in leaps and bounds. Really it has been stuck in the same place for a decade. Ninety percent of human genes are not studied because they are too complicated. These genes impact on people just as much as the 10 percent of "easy" ones. Most genes are inside cell nuclei so they are difficult to get to. However, dealing with the obvious is not sustainable. The 90 percent have to be studied. Hardly any funding at all is allocated to lesser known gene research. Scientific papers keep on regurgitating the familiar. PHD students have tunnel vision. Industry can provide a firm basis to examine the known. The little known has no industrial foundation. A study to apply existing learning tools to the neglected genes failed as people moved back to what is safe. Clearly, scientific principles are not being applied. Critical knowledge to identify what is true about DNA is being selectively ignored. Throwing out the

Bedbugs are the bane of humanity. Not only do they bite, but people are ashamed to say they suffer from the insects presence. Yet this is normal for any animal, and humans are no different from other creatures. Note how her face is obscured because of the shame Humans like to think that they are special and are somehow unique in nature. We evolved like other species alongside bugs who did well out of it. Indeed, humans even benefited while some bugs eat others. There are many of them: bedbugs, fleas, lice, ticks, scabies and so on. We have tried and failed to eradicate bedbugs. Humans must accept their presence. Dead bedbugs are found on the earliest mummies. Ancient Romans and Greeks wrote about them. Everything has been tried against them from dangerous chemicals to plants and potions. Even smoke has been tried to no avail. The only thing that worked was DDT. An entire generation enjoyed life for the first time without bedbugs. This was not to last, however

There are 1,200 species of the genus Pheidole . Each has developed to exist in a particular niche of the ecosystem. In a study of 300 species it has been found that certain species evolved similar characteristics independently. Species proliferated dramatically - from one to 600 species in the Americas. The evolutionary goal was to dominate all niches, first in the New World then in the Old. Expansion across one was independent of the other. Evolution took its own course. Ants are essential for healthy ecosystems. They aerate the soil, disperse seeds and help move nutrients. In biomass they equate with all vertebrates. Their study is indeed important ✴ Biology by Ty Buchanan ✴ http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://adventure--australia.blogspot.com/atom.xml . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
