Mitochondrial Eve
I believe that we have descended from a common maternal mitochondrial DNA line. Her name is Mitochondrial Eve. I am not a genius but I feel that it is possible that mitochondrial DNA could have mutated enough to cause slight changes over time.

Importance of Amphioxus
Amphioxus is a key organism for understanding evolution of the vertebrate genome. Scientists have discovered that each amphioxus gene correlates to either two or three vertebrate counterparts. Since amphioxus are in Phylum Cephalochordata and vertebrates, Phylum Chordata, I believe scientists are trying to link a connection between the two phlya. It seems that vertebrates could have evolved from cephalochordates by two successive rounds of whole-genome replication.

Polywater
Polywater was once thought to be a new form of water consisting of long chains or rings. Russian scientist Nikolai Fedyakin believed that he had created this because one of his experiments yielded a thick, syrup like substance made of only water. Later, Boris Deryagin came along and was able to produce the same results, but only in small quantities, the same as Fedyakin. He claimed that it was so stable that it's boiling temperature was around 1000 degrees Fahrenheit and it's freezing point around -40 degrees Fahrenheit. Rumors eventually spread that this new water, if released into the outside world, could turn other water into polywater and ruin the planet.
Polywater was eventually disproved because it turns out that the capillaries in which the water had "polymerized" had been contaminated. The polywater was just tiny particles.

fake websites
Fake Websites. There are an infinite number of sites on the world wide web that are fake. Some are less obvious than others and fool many people. I found quite a few while browsing the web the other day, but I have two favorites. The first is http://www.dhmo.org/facts.html and second is http://www.genochoice.com. How do I know these are fake? Well the first one explains how dihydrogen monoxide (aka WATER) is a toxic substance and merely inhaling it will kill you. Clearly they are mistaken and are only trying to freak people out. On the second website, you are able to create a baby with certain genes by scanning your thumb and your partners thumb on the computer at the same time. That is a little bit ridiculous.
