There are 100 Million Unnamed Species


Biology - 100 million unnamed species exist on the planet.
We know that many species on the planet are dying out. Apparently, we have nothing to fear. Though 2 million species have been named, a massive 100 million more are out there. This does not include currently unnamed bacteria.

Using clear categories will never be an adequate way to name species. Like human gene pools that are blurred across the world it seems that animals are also on a graduated scale, looking alike while being genetically different.

Each living creature is placed in a species category because it has independent evolutionary lineage. A horse and donkey for example are different species, but they both have a common ancestor. If they do breed their offspring are infertile. There is debate about this with claims that some mules have had young. This gets into the argument about Neanderthals breeding with humans when they have a different number of chromosomes. Interbreeding should not be possible.

The problem with naming is that animals from two species can look virtually identical. The African elephant is a misnomer. There are actually two species: the bush elephant and the forest elephant. One is genetically distinct from the other.

Day of Frankenstein has Arrived

The day of Frankenstein has arrived. New human beings have been born. The path of human evolution has been changed, and should I say damaged, forever. Even though a person can have three parents it should never have been done. Heaven knows what the long term consequences for the human species will be. Man could die out because natural selection has been bypassed for the first time in human evolution.
Now that Britain has passed legislation to allow such births, do-gooders in other countries are calling for its adoption too. Do they have the right to play God? They certainly do not! This affects every person living now and in the future. Consider the legal problems ahead for inheritance. Offspring will ultimately try to claim the wealth of a "host" egg provider when she dies. Your ancestors will be impossible to trace because some members of the population have three or more generations of three parents.

The problem with politicians is - They take knee jerk reactions and they are employed to run ministries in which they have no qualifications or skills. This also applies to voting in houses of parliament. Some politicians are as thick as a post and seem to have no commonsense whatsoever. Read the book Brave New World and see that it is really a stupid different world.

Eggs of Mussels Attract Compatible Sperm by Releasing Chemicals

Mussel sperm have to find the right egg. This is not as easy as it seems. When the eggs are released they can be scattered through ocean water or river. While mussels are attached to rocks, eggs and sperm are at the mercy of the elements. The eggs have to let sperm know that the eggs are available, so they send out a chemical message to attract suitable sperm.

Many species release chemical signals. The message sent has to be differentiated to prevent fertilization by siblings. A test was done forcing sperm to fertilize chosen eggs. Only compatible matches gave healthy offspring. In a later test mussel sperm were observed to choose compatible eggs to produce health young.

This is the first time chemical attraction has been observed in mussels. It shows how important compatibility is in many species. This brings into question the theory of gene pools where there is deemed to be no barrier to gene pairing. The idea that any male and female can have offspring no longer stands. Even human eggs send out chemical signals to attract compatible sperm. Some human couples cannot have children even when tests show they are perfectly healthy. Fertilization can occur with a different partner.
