Genetic testing (A.K.A genetic screening) is a type of medical testing that examines the DNA which shows any changes or alterations in your genes that may have cause illnesses or diseases. A genetic test can help confirm a persons chance of developing or giving a genetic disorder. Molecular genetic tests study the DNA's length and/or single genes to identify variations or mutations that have happened. Chromosomal genetic test analyzes the whole chromosome and the lengths of the DNA to check if any large/huge genes have changed. Biochemical genetic tests are used to study the amount of proteins which help indicates any changes that have been done. Also genetic testing is voluntary. Some of the examples that genetic testing can be done on is urine, blood, saliva, hair, and etc...

__ //**The Cons of Genetic Screening:**// __
 * Finding out that you have a disease that not much people have which shortens your life span and there is no cure to it causes stress and unwanted emotions.

 * It goes against some ethical choices which causes some controversies.
 * It could be kept confidential to the individual that volunteered.
 * Jobs could be denied by the genetics that you may have or develop.

This is a chart that shows some of the things that are tested and some of the benefits/risks.

This is a table that shows if genetic testing is a good or bad thing.

This is a pie graph that represents some adults thoughts and opinions on genetic testing.

This photo shows a very simplistic way to tell if there is a mutation or not in a gene test.

**__The Evolution of Penguins Becoming a Flightless Bird__**
First thing first, penguins date back to over 60-65 million years ago. They are believed to be the decedents of the birds that were on this Earth. Throughout the millions of years, penguins spent more time in the water then land which ended up developing so called flippers. These flippers are just a reconstructed version of wings that they once had. It is believed that the evolution of them becoming flightless occurred very slowly. This photo shows the evolution of the penguin's wings and flippers. The top bone structure is what they believe were the penguin's wings during the early age of them. The bottom bone structure is what the penguins have for a bone structure during this age.

It is believed that they forgot how to fly during their evolution but they are not the only birds that forgot this ability. When they had the small and thin bones, it decreased the weight of them which was good for flying. Though, throughout the million of years, penguins developed these heavier and bigger bones that are filled with marrow which made it harder for them to fly. Although their wing structure did change to flippers, they didn't really have much of an use to fly. Instead they were able to feed from the water. Through everything that changed in their bone structure it helped them be able to adapt to environment that they were in. This also helped them not become extincted. This is a small timeline that shows the evolution of some of the penguins. This is a photo of them swimming. This is a cute photo of 2 baby penguins communicating with each other.
