A study dating the age of more than 1 million single-letter variations in the human DNA code reveals that most of these mutations are of recent origin, evolutionarily speaking. These kinds of mutations change one nucleotide – an A, C, T or G – in the DNA sequence. Over 86 percent of the harmful protein-coding mutations of this type arose in humans just during the past 5,000 to 10,000 years.

Some of the remaining mutations of this nature may have no effect on people, and a few might be beneficial, according to the project researchers. While each specific mutation is rare, the findings suggest that the human population acquired an abundance of these single-nucleotide genetic variants in a relatively short time. (more…)

Dating today is hard. Trying to find someone with common interests while avoiding the nightclub scene can be daunting. It is especially difficult to meet a person who is interested in a long-term relationship and not a one-night stand. Online dating has opened the door of opportunities for many people and has become extremely popular. More couples are connecting via the Internet and sites devoted to creating relationships.

Choosing a Dating Site :

There are so many dating sites available now that it is difficult for individuals to settle on one particular site. One of the best recommendations is to select a site that has a solid reputation and has been around for a while. Sites such as eHarmony, match.com, zoosk, and chemistry.com are only a few of the sites that are available with positive reviews, a large membership, and a good track record. They base their connections on personality traits, chemistry, and finding things in common for a starting point. Those interested can find out who is in their area with similar philosophies and goals in life. Dating sites give a person a starting point and they can search through profiles to narrow down the selection before going out on a date. (more…)
