Evo-devo biology involves cross-species comparisons of entire developmental trajectories, not just of adult forms. This approach has proven very successful in general morphology, but its application to neurobiological problems is still relatively new.

Carbonaceous chondrite meteorites are carbon-containing fragments of primitive asteroids that have offered the only samples available to date giving insights into chemical evolution in laboratory analyses. Their study has revealed that abundant organic chemistry came to be in the Solar System ahead of terrestrial life and, by the input of these meteorites and comets, might have aided in the origin of our planet’s biochemistry.

The question of the origin of life cannot be explained by appealing exclusively to Darwinian evolutionary mechanisms, as many experts tend to assume, but requires a profound change in perspective.

ancestro universal

The cenancestor is defined as the last common ancestor of every currently living being. Its nature has been inferred from the identification of homologous genes between archaea, bacteria, and eukaryotic lineages. These inferences indicate that the cenancestor had a relatively modern protein translation system, similar in complexity to that of a current cell. However, the key enzymes for the replication of genetic material and for cell membrane biosynthesis are not homologous in bacteria, archaea, and eukaryotes. Here, we briefly review the history of the concept of the last universal common ancestor and the different hypotheses proposed for its biology.
