Good day po, Ma’am! In response po to your questions:
1. The lateral line po refers to the ancestor that is currently at the root of the phylogeny from which the first “ear” came from. This ancestor is called the lateral line or aquatic vertebrates due to their sensory organ (the “ear”) that detects movement or vibration through the water.
2. As of now, the current knowledge on the root ancestor for the ear is largely unknown and is still under continuous discussion. However, the current accepted hypothesis are those stated in the recording, the acousticolateralis and the ancestor sensory cell hypotheses), where the former states that the mammalian ear came from a lateral line of aquatic vertebrates while the later states that there is an ancestor that possessed a sensory cell. These hypothetical ancestors gave rise to the current mammalian ear which is a lot more complex and specialized in both morphology and physiology.
That is indeed a good point to consider. There are currently studies being performed to implement neural stem cell transplantation to treat hearing loss. However, there this treatment has yet to be approved for clinical use where local hormone injections, hyperbaric oxygen chamber rehabilitation, hearing aids, cochlear implantation, etc. are the treatments utilized at the moment.
