There are greater contrasts in humanity’s collective standard of living than ever before. As of 2014, Bill Gates topped the list of the world’s richest people for nearly all years of the previous 20. In 2000, his net worth was about $100 billion, or about the same as the collective wealth of the poorest hundred million Americans or the poorest half of humanity. Although Gates and other high-technology billionaires can live , for one person to possess the same level of wealth as billions of people collectively is a recent phenomenon. In 2014, about 30 thousand children died each day because of their impoverished conditions.

Mendel was not the first to experiment with heredity, and our Lyman Briggs biology class will not be the last to deal with genetics.

One of the most notable geneticists was Gregor Mendel

A has challenged The Expensive-Tissue Hypothesis, at least as far as robbing energy from the digestive system to fuel the brain. The study compared brain and intestinal size in mammals and found no strong correlation, but there was an inverse correlation between brain size and body fat. But since human fat does not impede our locomotion much, humans have combined both strategies for reducing the risk of starvation. Whales have bucked the trend, also because being fatter does not impede their locomotion and provides energy-conserving insulation. A human infant’s brain uses about 75% of its energy, and baby fat seems to be brain protection, so that it does not easily run out of fuel. However, the rapid evolutionary growth of an energy-demanding organ like the human brain seems unique or nearly so in the history of life on Earth, and comparative anatomy studies may have limited explanatory utility. There are great debates today on how fast the human brain grew, what coevolutionary constraints may have limited the brain’s development (, , ), and scientific investigations are in their early days.

I learned from my middle school years, that Gregor Mendel’s experiment on pea pods is an example of genetically modified foods.

With that separation from physical reality, speculation frenzies have been major aspects of how stock markets operate. The first bout of market insanity was the . The slave-trade frenzy that fortune was less than a century later and was a stock speculation issue. The , in which greed and fear prevailed. The USA has devolved into the serial bubble economy as its empire has declined, and until the crises of the early 21st century, the USA’s previous market mania was in the 1920s. Back then, companies with nothing more than “” behind them sold stock to the public. It was essentially no different from the that . Those orgies of greed were usually associated with some new product, market, or a financial sleight of hand to finance them. The 1920s bubble was sandwiched between World War I and its sequel, and a . , and there was even a , backed by leading industrialists and politicians who tried to entice into becoming their front man.

He becomes a creature of great disappointment and sullenness, not helped by his parents’ obvious resentment towards him....

Forests were a radical innovation that has not been seen before or since. Trees were Earth’s first and last truly gigantic organisms, and the . Why did trees grow so large? It seems to be because they could. Land life gave plants opportunities that aquatic life could not provide, and plants “leapt” at the chance. Lignin, first developed for vascular transport, became the equivalent of steel girders in skyscrapers. In the final analysis, trees grew tall to give their foliage the most sunlight and to use wind and height to spread their seeds, and in the future that height would help protect the foliage from ground-based animal browsers. The height limit of Earth’s trees is an energy issue: the .Arid climates prevent trees from growing tall or even growing at all. Energy availability , too. From an ecosystem’s perspective, the great biomass of forests was primarily a huge store of energy; trees allowed for prodigious energy storage per square meter of land. That stored energy ultimately became a vast resource for the forest ecosystem, as it eventually became food for other life forms and the basis for soils, which in turn became sponges to soak up precipitation and recycle it . Trees created the entire ecosystem that depended on them.

Land colonization was perhaps the Devonian’s most interesting event. The adaptations invented by aquatic life to survive in terrestrial environments were many and varied. Most importantly, the organism would no longer be surrounded by water and had to manage . Nutrient acquisition and reproductive practices would have to change, and the protection that water provided from was gone; plants and animals devised methods to protect themselves from the Sun’s radiation. Also, moving on land and in the air became major bioengineering projects for animals. Breathing air instead of water presented challenges. The pioneers who left water led both aquatic and terrestrial existences. Amphibians had both , and arthropods, whose exoskeletons readily solved the desiccation and structural support problems, evolved to replace their gills, which were probably book gills.
