What is the advantage in having this number of lobes compared to organisms with fewer number of lobes?

An advantage of having a four chamber heart is that it keeps oxygenated and de-oxygenated blood separated, so there is no mix between old and fresh blood. This allows the blood leaving the heart to have far more oxygen than it would otherwise. Also, having a four chamber heart allows more power to supply the body with energy and oxygen rich blood.

∙ 11y agoThere are multiple "lobes" you could be referring to - lobes of the brain, lung lobes or liver lobes come to mind. In the brain, the advantage of having more lobes is the increased mental processing capacity, often referred to as "intelligence". In the lung and liver, the advantage for more lobes is the ability to segregate infection and protect the rest of the organ from disease.
