Biofeedback is stress-reduction technique whereby electronic equipment measuring a person’s involuntary (neuromuscular and autonomic) activity helps him gain a level of voluntary control over these processes.

Biofeedback therapy will help you to relax and control involuntary response related to stress like heart rate, sweating, temperature and blood pressure. The electronic equipment will let you know when there is any sign of stress, therefore you know when to calm down yourself.

The evolution of molecular biology has made possible to establish a new classification of all organisms according to their DNA, and it's called phylogenetic classification. This classification group living beings according to their kinship it is established according to anatomical, and especially genetic, based on the similarity of genes between species.

This made it possible to discover kinship ties between species of which there is no suspicion of any morphological link between them, something which the old classification (the traditional classification) was incapable of doing (and this proves the importance of the DNA and genes in organisms classification.
