Defending the Christian Worlview, Creationism, and Intelligent Design

This is my personal virtual library, where i collect information, which leads in my view to the Christian faith, creationism, and Intelligent Design as the best explanation of the origin of the physical Universe, life, and biodiversity

1The green sea slug Empty The green sea slug Sun Mar 16, 2014 11:42 pm


The green sea slug drifts around the shallow shores of the Americas doing a pretty good impersonation of a soggy leaf. A cousin of the humble snail, this aquatic escargot only eats algae. After fueling up the tank on a few good meals, the green sea slug is done . . . like, forever. Thereafter the green sea slug can get all of its energy from the sun, like a plant.

It’s one of the only animals on earth that can photosynthesize. It does this by stripping the tools that the algae uses, the green photosynthetic organelles called chloroplasts, and storing them in its skin cells. It steals from algae so that it can become solar-powered. That’s pretty amazing, but eventually the chlorophyll in these structures will run out.

Fortunately the green sea slug can simply produce more. It should be impossible. Scientists don’t really understand it, but somehow the green sea slug has managed to incorporate enough of the algae’s DNA into itself that it can produce chlorophyll.

Once the slug has some chloroplasts to hold its chlorophyll, it can live on sunlight alone. It doesn’t eat or produce any waste after that. That would be like us gorging at a salad bar, then never needing to buy food or toilet paper ever again.

This animal had caused quite a stir in the scientific community when it was discovered that it ran on solar energy. Known as the "Solar Powered Sea Slug", this creature inhabits the Atlantic seaboard of the United States and has a green, gelatinous, leaf-shaped body. Scientists have quentioned how this sea slug can run on solar energy, but finally, Mary Rumpho of the Univerity of Maine has discovered the answer. According to her, this sea slug obtain chloroplasts, the organelles in plant cells that are responsible for photosynthesis, from the algae that it feeds on and then stores those stolen chloroplasts in the cells that line its gut. However, the main question Rumpho is facing is "how?".

There are several possibilities. Rumpho had later discovered that the Solar Powered Sea Slug had vital genes essential to algae photosynthesis in its DNA. A possibility is that when the sea slug feeds on the algae, not only does it takes the chloroplasts, but it also takes some of its genes and incorporate them into its own DNA. Then, those "stolen" genes would produce proteins that would continue the photosynthesis process of the "stolen" chloroplasts. Discoveries have been made that these "stolen" genes can be passed down to the next generation.

From all this, one can fantasize when animals or even humans can obtain the ability of photosynthesis. Discoveries were made that young Solar Power Sea Slugs can survive for the rest of their year-long lives after eating algae for two weeks. If humans could do the same and live off the energy of the sun, it could solve a lot of problems involving food shortages and environmental concerns. Unfortunately, scientists have agreed that there is no possible way for humans to do the same with their own digestive systems.
