been described with many organs with traits of taxonomic interest – especially the ampulla, the prostate, the penis and the copulatory bag – which have helped to establish an evolutionary trend of the genus at a global level. Specifically, in the Doto genus, experts note a progressive reduction of the copulatory bag, and a connection of the seminal receptacle with the proximal part of the female or female nidamental glands. An extreme habitat to find new bioactive molecules The Antarctic continent contains very particular habitats that are difficult to study. Much of the research work of the team led by Professor Conxita Àvila focuses on identifying the molecules that intervene in the relationships between these organisms and evaluating their possible pharmacological use.

“We are trying to find out what chemical Cameroon Email list defenses these marine invertebrates use to repel predators, to make room or to keep themselves clean and prevent organisms from adhering to the surface,” says Conxita Àvila. “These chemicals may also have potentially useful biological activity in the form of drugs,” he adds. “Only one natural product of a species of Doto from the Atlantic Ocean has been described ,” Àvila continues, “but it is believed that the glands located in the dorsal expansions or cerata are responsible for accumulating deterrent substances against predation. In the case of Antarctic species, there is not yet enough information on these aspects of chemical ecology. ‘ For now, the evolutionary scenario of the Dotidae family remains full of phylogenetic unknowns to be resolved.

Although it is still considered a family belonging to the clade Dendronotida, it is necessary to define the synapomorphic characters – that is, shared by two or more taxa – that clearly group the Dotidae with the other close families. According to the experts, it would be necessary to obtain and sequence enough representatives of all these taxa and analyze them with phylogenomic techniques to be able to solve the evolutionary unknowns that these marine invertebrates hide.the global fight against the pandemic.gene or its location in the genome in different groups of organisms ), reinforces the importance of gene loss in the evolution of species ”. Losing to Win: An Evolutionary Paradox Traditionally, it was believed that insects had a knack for losing genes; but the sequencing of the genome of Tribolium castaneum ,
