Dangerous chemicals in human breastmilk?

On May 16 of 2012, NPR did an author interview with Florence Williams on "Fresh Air." She told them that she had two children. She was nursing with her second child when she read a research study about the toxins human breast milk. She became curious and decided to send a sample of her own to a lab in Germany. The results of her test surprised her. Pesticides. Dioxin. An ingredient of jet fuel. All found in the sample. How, though? How would the chemicals get in there, anyway? "It turns out that our breasts are almost like sponges, the way they can soak up some of these chemicals, especially the ones that are fat-loving — the ones [that] tend to accumulate in fat tissue," Williams tells Fresh Air's Terry Gross. "Unfortunately, the breast is also masterful at converting these molecules into food in the way of breast milk."

How are homo-sapiens related to primates?

Several species of primates, such as orangutans, gorillas, chimpanzees, and other extinct species, are considered evolutionary relatives of humans. The truth behind it is all in the DNA. Also, the idea is taken from the similarities in the anatomy of a chimp compared to a human. As you can see in this image, there is 98% genetic similarity. That's only two percent of a genetic change. Coincidence? Many people would argue not. Interesting, right? The primates fall into the hominids family, as do humans, so we're classified as similar creatures. The neural systems of chimps are actually slightly more advanced than most animals, and can sometimes be trained to do work for humans, like carrying things and helping with various tasks. There are also chimpanzees that are trained to speak, in a human way, and be able to communicate with humans. In a way, it's another form of grouping them with humans, and categorizing them in a single classification with us. For more information, go to the site below-
