Imagine a unique version of Earth where the Sun is an L-type brown dwarf, a type of low-temperature and low-luminosity star. This alternate solar system offers a distinct set of conditions for life to thrive. In this hypothetical scenario, plants have adapted to capture energy from the Sun by using phycoerythrin instead of chlorophyll. Phycoerythrin is a red pigment commonly found in certain types of algae and cyanobacteria. With this alternative pigment, plants on this Earth appear reddish in color, as they harness the red and far-red light emitted by the brown dwarf. Furthermore, the oceans on this Earth are distinctively unique due to their high concentration of iron oxide. Iron oxide imparts a reddish-brown color to the water, presenting a striking visual contrast against the red-hued flora growing on the land. The presence of iron oxide influences the chemical composition of the oceans, resulting in different biogeochemical cycles and potentially altering the behavior of marine organisms. In this Earth variant, organisms, including humans, utilize a different form of respiratory pigment instead of the commonly known chlorophyll-based hemoglobin. Hemoglobin allows for oxygen transportation in the bloodstreams of many organisms, but in this hypothetical scenario, the blood cells have evolved to use a unique variation of hemoglobin suited for this distinct environment. Overall, this alternate Earth presents a fascinating glimpse into an ecosystem shaped by the peculiarities of a brown dwarf star, phycoerythrin-based plant life, iron oxide-rich oceans, and a modified form of hemoglobin in the bloodstream.
