DailyDirt: Biological Curiosities
from the urls-we-dig-up dept
Biology always seems like the messy and gooey branch of science. Biology contains a bunch of strange phenomena that seemingly exist just because they're possible. Here are just a few quirky biological discoveries.- Asteroids could have been the original source of chirality in our biological history. Some carbon-rich meteorites seem to have an excess of L-isovaline (a chiral isomer of the biologically important amino acid, L-valine), but the reason why the excess exists is still a mystery. [url]
- There's a type of slime mold that has been dubbed the 'smallest farmer' -- since it can store and grow its own food. The single-celled amoeba eats bacteria and carries around its favorite food just in case local supplies run out. When it eats up all the bacteria in its neighborhood, it moves on and grows bacteria where it settles down next. [url]
- Japanese researchers have created a genetically engineered mouse that tweets like a bird. The research is supposed to investigate the origins of animal language, and it'll be really amazing when they grow a mouse that can tweet... on Twitter. [url]

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

Engineers have engineered a car in hopes that we can figure out how it evolved on its own.

Its still a mouse...
Creationists view of natural selection (ie natural selection is a biblical concept):
http://www.answersingenesis.org/articles/2011/02/26/news-to-note-02262011
Creationists emphasize 'kinds' that adapt (but inherently still of that kind). For example: a poodle, a collie, and a german sheperd are all dogs which have different characteristics, but doesnt make them any less dogs. These different dogs all have a common ancestor, which also, not coincidentally, was a dog. Due to natural selection and the conditions of their environments, the different dogs adapted to survive.

From the above link I want to quote in particular:
For years, creationists have emphasized a “kinds” model of biology (and thereby established the field of baraminology). This model starts with the Bible’s description of God creating unique “kinds” of plants and animals (and man as distinct from any animal kind), then applies what we know about natural selection and various genetic processes to understand the biological diversity we observe today. Rather than all creatures descending from the same original organism—a “tree” model of life—all creatures descend from the progenitors of their kind—an “orchard” model. Thus, the whole range of canids, from domesticated dogs to wolves to jackals and beyond, constitutes the diversified members of the original “dog” kind. And the confusion over the taxonomic placement of the Egyptian jackal reminds us of this biological reality.
