For a while I have been toying with the idea that mosquitos and other insects that draw blood and body fluids may be the mechanism that nature uses for the evolution of species. To me, nature and the whole Universe are "organic" and everything has a purpose, even if sometimes is not so evident. In the case of the mosquito, I was puzzled since its very nature (to draw blood from us, plus to inflict a little pain, plus to transmit diseases) seems antagonist to man. Sidhartha Gautama, the Budha said 2600 years ago: "Everything living is sacred", but with the mosquito, my respect for life was put to the test. Now, a mosquito draws blood from one species and transmit it to another member of the same species or another species. He is transmiting genetic material: Genes, viruses, DNA, prions, or other type of genetic material. If it is a virus, once inside the new host, it will duplicate until the whole body is saturated. Remember there is a lot of similarity between some viruses and genes. The change is produced very fast compared to what it could take to other mechanism as mutation (produced by radiation or other mechanisms) which it will have to wait to see if the offspring is able to survive with the new change. Of course whatever change to be preserved would have to have a survival value. In this way the new genetic material is "absorbed" by the host while alive (here part of the test is if the host does not die). Now, the host when he has offspring, they will carry the new genetic material. In this process mosquitos and other insects would do a most needed job for the evolution of the species; something simillar to what bees to with their process of polination for the plants. Please, those who have the tools to put these simple idea to the test, do so and let me know what you think about it.

Actualy we DO have much non-human DNA as part of our own DNA -> HERVs are Human Endogen RetroViruses: if you are infected by a virus (retrovirus in this case) and your gonadesīDNA gets to include the virusī genes, your offspring will have itīs genes as part of their own genome. That has happend a lot to us. Most HERV secuences are harmless since they have been "dissabled" by mutations; but some are just waiting for the conditions to trigger an infection - by a virus that infected - not you, but one of your forfathers. Amazing, isnīt it? Some examples are some MMTLVs (Mouse Mamal Tumor Like Viruses)- HERVs linked to Mamal Cancer Now you know enough to run a large search on the subject on the net Corvus Albus IP: 200.52.2.161 |
