DailyDirt: Life, But Not As We Know It
from the urls-we-dig-up dept
We’ve noted before that the classification of living things is a bit tricky. It’s not just plants and animals anymore. Biologists are continuously discovering creatures that defy the old taxonomies. Here are just a few more examples of the incredible diversity of life on our planet.
- Christoph Adami tries to define life — by studying artificial life and the characteristics of information processes that seem to behave like life. His self-replicating programs evolve and create virtual ecosystems — and could help figure out how to find extraterrestrial life. [url]
- Biologists thought they had only cataloged about 10% of all fungal species. But there could be a whole different domain of life that is similar to fungus, but isn’t. [url]
- Mantaphasmatodes is the first new insect order discovered since the 1900s. And these insects are almost everywhere. [url]
- To discover more interesting biological curiosities, check out what’s currently floating around the StumbleUpon universe. [url]
By the way, StumbleUpon can recommend some good Techdirt articles, too.

?Kingdom?, Not ?Domain?
?Domain? is a whole level of division above ?Kingdom?. Thus, all the eukaryotes (made up of large, complex cells with separate nuclei and two or more genomes) form one ?domain?, within which you have the ?kingdoms? of plant, animal, fungus and this new one.
And alongside the eukaryotes, you have the archaea and bacteria, two more domains of small, single-celled organisms which are considered more different from each other than plants are from animals.
Re: ?Kingdom?, Not ?Domain?
From wikipedia: Research in the 21st century does not support the classification of the eukaryotes into any of the standard systems. As of April 2010, the situation appears to be that there is no set of kingdoms sufficiently supported by current research to gain widespread acceptance; as Roger & Simpson say: “with the current pace of change in our understanding of the eukaryote tree of life, we should proceed with caution.”
Kingdoms and Domains are hard definitions to maintain when organisms don’t really care about being classified… 😛
