Franscois Gohier Bottle Nose Dolphins Indian Ocean (Tursiops aduncus)
MICHIGAN, FISHWORLDs.com - Dolphins are known as intelligent marine mammals. He had an advantage in communication with his countrymen and be able to interact with humans. Intelligence of dolphins and even beat some other mammals. What makes dolphins intelligent?
Michael McGowen from Wayne State University School of Medicine in Michigan interested in knowing why by performing molecular analysis.
"We decided to look at the genes in the genome of dolphins to see if there are similarities between the genes that changed in dolphins with a gene that turns on the primate family," said McGowen.

Michael McGowen from Wayne State University School of Medicine in Michigan interested in knowing why by performing molecular analysis.
"We decided to look at the genes in the genome of dolphins to see if there are similarities between the genes that changed in dolphins with a gene that turns on the primate family," said McGowen.
In research, McGowen analyze 10,000 genes in bottle nose dolphins. Later, he compared with other animals, such as cows, horses, dogs, elephants, chicken, platypus, and human. Note, cattle are the closest relatives of dolphins. By knowing the gene changes or mutations, McGowen can know which of the selected genes or being evolved. If a dolphin has more protein associated mutations, it could be inferred active dolphins evolved.
The results showed that 200 genes dolphins drastically changed. 27 genes which are related to the central nervous system. While there are other genes associated with metabolic changes.
In connection with the change in brain-related genes, McGowen was quoted as saying by LiveScience, Wednesday (06/27/2012), said, "Maybe this could lead to changes in gene cognitive capacity that can be seen on the dolphins."
In the study, researchers also found that dolphins evolved more slowly. This may be due to "selection" of dolphins to produce fewer offspring and invest more afterwards with nurturing. The research results published in the journal Proceedings of the Royal Society B, published today.
