The Current Evidence of Human Evolution - Essay Example This study, according to Keim (2011) supported the idea that increasingly younger birth ages are hugely influenced by changes in the genetic makeup caused by natural selection. This means that the ability of a woman to give birth at a younger age is dependent on the inherited genetic traits, according to Keim (2011). This evidence provides a clue as to how Homo sapiens evolved into a species. Another research conducted in Northern Europe and Africa has shown evidence of human evolution. According to this study, it was discovered that people living in these regions have developed the ability to tolerate lactose in their diets. This form of evolution, according to scientists was due to cultural reliance on milk as a product of agriculture (Harrel 2009). Ways in which current understanding of human evolution effect how we may evolve in the future? From the current evidence of modern evolution, it becomes apparent that humans may continue to evolve in the future. This is attributed to th e selective pressures that humans are likely to encounter in the future thereby resulting in continued evolution. For instance, we might make an educated speculation that future human beings might end up lacking the wisdom teeth (Wade 2010). Research indicates that a majority consider their wisdom teeth as things that should be removed surgically before they begin to erupt. The main reasons being that modern humans have small jaws that do not require wisdom teeth. The main belief is that, wisdom teeth are vestigial molars, which evolved in ancestral humans at a time when jaws were bigger, and most diets were hard that required strong jaws. It is no wonder wisdom teeth continue to disappear. For instance, research indicates that about 35% of people are nowadays born without wisdom...

The Major Issues and Difficulties Facing the European Union and Its Attempts to Effectively Fight Fraud Against Its Budget - Essay Example In 1992, the Treaty of Maastricht was signed which gave rise to the European Union (EU). A single market devoid of any boundaries was established where people could go from one country to another freely. The single currency concept came into being in 2002 with the introduction of Euro. The EU family is growing day by day and more countries are joining in. The European Parliament, the body governing the EU, takes care of all the activities of the member states. The member countries set up the parliament by giving their votes. The votes are directly proportional to an individual country’s size. The parliament consists of Commissioners of different countries led by a President. (History of European Union, n.d.) With the enlargement of EU, more countries came into its fold. The challenge for the EU was to induct these countries into its set up. The problem faced by EU in this regard was that the Parliament was influenced by the bigger countries as they had the lion’s share of commissioners. The treaty of Nice underlined that the small countries will get to cast a minimum amount of votes while the big countries would cast the bigger share. This means that the bigger countries will influence all the decisions taken in the EU. (The treaty of nice, n.d.) Perhaps, the main issue facing the EU right now is the fraud against their budget.

Despite the measures taken by the EU in controlling the frauds, various scams, and frauds surfaced which has led to the decrease in public trust on EU.
