When was red algae discovered

Using synchrotron-based X-ray tomographic microscopy the team was able to peek inside the fossils, which contain structures similar to those found in red algae.

The team identified platelets within the fossils that they believe were parts of chloroplasts, an organelle in plants where photosynthesis takes place. As George Dvorsky reports for Gizmodo , prior to this find, the oldest-known complex multicellular organism was Bangiomorpha pubescens , a type of fossilized red algae discovered on Somserset Island in the Canadian arctic dated to 1.

A recent study suggests that single-cellular life arose on earth some 3. And those life forms dominated the planet for around 2. But sometime between 2. But how did it happen? These fossils could help pin down when this switch occurred, Debashish Bhattacharya, an evolutionary biologist at Rutgers University tells Ross. It has now been proven to be a formerly unknown species with its closest relatives in the North Pacific. It is relatively common near the southwest and west coast of Iceland, along the Northwest peninsula, and has been found at one location along the colder north coast.

MFRI is currently experimenting with growing the algae as a food supplement in collaboration with Hyndla ehf.

Science News. Ecosystem engineers in the making 'The fact that coralline red algae occur so much earlier in the Earth's history sheds new light on several issues in ecology', says Teichert. Coralline red algae from the Silurian of Gotland indicate that the order Corallinales Corallinophycidae, Rhodophyta is much older than previously thought.
