 * What is Down syndrome?**

In genetics it is learned that normally a human inherits 23 pairs of different chromosomes, 23 from their mother and 23 from their father. Down syndrome is caused by having an extra copy of chromosome 21 inherited by on of their parents giving the child three chromosome 21's. When it comes to chromosomes being inherited by one parent, two is //not// better than one.




 * How does Down syndrome affect the individuals with it?**

Individules with Down syndrome share characteristic facial features. In the two pictures about these are two children that are not related but both have Down syndrome, their facial features look similar. It is not the facial features that matter but the health that effects those with the disease. Those with Down syndrome experience learning disabilities, delays in development, heart problems, gastro-intestinal problems and are at risk for early onset Alzheimer's disease. More health issues apply to those with more severe cases of Down syndrome.

In this video Dr. Moscatel talks about how there is a test for pregnant mothers to see if their child has Down syndrome. When my mother was pregnant with my little brother the doctors had said that he was going to be born with Down syndrome. These tests do not always prove to be correct for my brother turned out to be a healthy baby.

 * Facts!**

Dr. Jerome Lejeune in 1959 identified the extra chromosome 21. 1 in every 800 babies born are born with Down syndrome. 80% of babies born with Down syndrome are born to women under the age of 30. Dr. John Langdon Down was the first to indentify Down syndrome, but because he himself did not have Down syndrome there is no ownership to (Down), if he did have ownership it would be called Down's syndrome.

Wiki Post #2 Evolution January 13, 2013



Music that we listen to today is not the same music that was listened to hundreds of years ago. Music has evolved.

How has it evolved?

For something to evolve it needs to have a pressure that forces it to change in order to have an advantage. With music, its change is influenced by culture and what is happening in society at the time. For example, in the 1960's the music that was popular was Psychedelic Rock, which would be the Beetles, Bob Dylan, ect. It was Hippy music because it was light and fluffy it is not the same as the music listened to in the 1600's which was more serious and played on the piano because it suited the people of that time, high-class English gents, enough said.

The video below goes through different time periods and the music that was played in those time periods.

Can you see how the music has changed which the time and people that it was played in?

When looking at the music from the 1920's to 1950's the music was not too different. Evolution doesn't work in a fast pace, and the time between those two time periods is only a matter of decades not centuries. Now, if you compare the music in the 1920's - 50's to the 900's - 1800's there is a huge difference with the music because there was a huge difference in culture and society.



If music does not evolve to fit with what the society and the culture demand at the time it will fade out and not be popular anymore. For example, classical music does not even compare to Dubstep in today's time because the popular demand of the people is for upbeat dance music. If you asked the young generation today what they like more, dance music or classical, classic would go down the drain because it does not have the advantage like dance music does to fit the demands of todays society.

These guys have their own style on the music from 1960 to today. There is some swearing towards the end. I had to include another video by them just below not only because it's hilarious but to show the difference between the 70's music, the Hippies, the classical music, rock and our more modern "top 40's music.
