Where's My Mommy? : mitochondrial eve

Mitochondrial Eve is said to be the mother of all daughters. How is this possible? Mitochondrial DNA is passed from generation to generation women, unchanged. Meaning, all women alive today descended in a direct unbroken female line from mitochondrial Eve. As population grew, people started to migrate away from “home”, there physical appearance became proportional to their environment. For example, darker skin is the indirect result from the sun. We know that too much sun is bad for you, so in order for these people to survive in the condition, a mutation had to be made. Those who survive were able to make that adjustment. We now know that the “adjustment” is melanin. Mutations such as these, occurred everywhere there was people. And then when populations grew there, the people of the new cites migrated, resulting in more mutations to adapt to new environments.



97-99% of every human genes are the same. Here is the 3-1% that makes us all unique.

poly water

Poly water or anomalous water or orthowater is liquid water formed by the condensation of water vapor. This water has lower vapor pressure, lower freezing temperature, higher density and viscosity, higher thermal stability, and different infrared and Raman spectra, compared to the water that we originally know that flows out of our faucets.1 Anomalous water was first discover in 1967 at the Russian Technical Institute. It was the properties of water and the effects of confined spaces on liquids that contributed to the widespread interest in anomalous water.2 However, Many researchers discovered that anomalous water is not a polymeric form of water and that it is in fact dissolved glass.3

Weird Website

Ok so these people are talking about freezing people so that they can preserve the living. But they don't call it freezing, they call it vitrification, which is not freezing but preserving similar to what they do to the animals you dissect, I suppose. Their goal is to preserving human life with the intent of restoring good health by cryonics. By preserving human "life in a state that will be viable and treatable by future medicine. It is expected that future medicine will include mature nanotechnology and the ability to heal at th cellular and molecular levels." Fact or Fiction?

Why know amphioxus?

You may know them as lancelet and in some part of China they are considered a fishing industry. These small marine animals resemble small fishes with out eyes and spend most of their time buried in the ocean's bottom (Britanica). The lancelet are representatives of the subphylum Cephalochordata, sister group of craniates.
So why know about these small creature that live at the bottom of the sea? Well, they provide indications about the origins of the vertebrates. These traces are found in their genomes that holds clues to evolution. Clues such as how vertebrates have employed old genes for new functions(Wikipedia).
