The idea of a living fossil is rather intuitive. We think that a kind of organism deserves that denomination if it has been living in the planet during a very large period of time apparently without any change. A […]

Although we assume evolution of complex life forms as a matter of fact, we must admit that our brains are not ready for such an odd concept. Even though we can slightly imagine what a million year means, when we […]

Nowadays there are still people that believe in destiny. However the scientific community more and more is bringing light to that subject showing that although the genetic material could program ourselves to suffer some pathologies, the day-to-day experiences are the […]

Think on a cell, it is alive and, among other things, it lives to reproduce itself. The paradigm of cell division is the mitosis, a wonderful dance orchestrated to equitably distribute the possessions of the mother cell: molecular structures, machinery […]

There is a strong tendency to consider that every scientific or technical solution to a particular problem is irrefutable. Nowadays, scientific and technological knowledge usually eludes public criticism and even we have seen how important government decision making were made […]

The genome is the text of life. Its ink is the deoxyribonucleic acid (DNA), a heteropolimer of four nucleotides (guanine, adenine, thymine, and cytosine). It encodes the instructions to make work all known living organisms (and viruses). It was isolated […]

When the general media report news about genetics, there is a deplorable tendency towards gene determinism. Headlines in the vein of “Gene for X discovered”—where X is anything from a physical trait to a complex behavior—are regrettably common, and almost […]

It is interesting how some ideas get stuck in our minds even long after it is proved that they are incorrect or incomplete. Haeckel’s Recapitulation Theory, which states that during the embryological development of an organism it undergoes through different […]

The advances in molecular biology and the so called post-genomic era, have improved significantly the fight against many human diseases, in some cases almost leading to their eradication. However, there are still regions of our planet were people suffer from […]
