Genetics, gymnastics, and getting to know the sauteur d'Alfort rabbit | |
Some rabbits walk on their front feet with their back legs in the air A gene defect may make rabbits do handstands instead of hop Alfort jumping rabbit: Scientists solve mystery of handstanding rabbit A loss-of-function mutation in RORB disrupts saltatorial locomotion in rabbits Lesson Plan: Run, Jump, Swim or Fly, a lesson on Heredity Unit 4: Molecular Genetics and Heredity of Livestock Many readers have likely witnessed a bunny hop, but new research confirms some rabbits are capable of other impressive moves; namely, some rabbits travel by handstand. Though the first accounts of these handstands occurred back in the 1900s, a recent research study clarified why this type of movement occurs. The research focused on rabbits known as sauteur d'Alfort, a breed that is incapable of two-footed hops, a type of movement labeled "saltatory locomotion." Accordingly, the rabbits resort to a more creative form of movement: shifting onto their front legs, hoisting their hind legs in the air, and traveling by handstand (or pawstand). Miguel Carneiro (University of Porto, Portugal), Leif Andersson (Uppsala University, Sweden), and colleagues conducted breeding experiments and concluded that the rabbits' locomotion phenotype was the result of a mutation in the RORB gene (short for "RAR related orphan receptor beta," a protein coding gene). In addition to adding context to the light-hearted images of balancing bunnies, this research also has serious implications, as it allows researchers to better understand how the spinal cord works. While researchers continue to investigate these connections, readers can marvel over the power of science: "one defective gene might turn some bunnies' hops into handstands." [EMB] At the first link, readers will find Michael Marshall's piece for New Scientist, which provides an overview of the genetic mutation and a cute image of the rabbit gymnastics in action. Readers will learn more about the mutation (including another species in which it has been discovered) at the second link, which leads to Erin Garcia de Jesus's reporting for Science News. The third link, from BBC News, echoes the previous article's point that connections between genes and jumping are not just important for rabbits; for example, kangaroos also rely on "jumping-related genes," to hop around. Readers will find the research paper, published last month, at the fourth link. Educators looking to use this news story as a launching pad for a lesson on animals, genes, and heredity may enjoy the fifth and sixth links. The fifth link leads to a lesson plan from WyoBio, a Wyoming-based citizen science initiative, that is appropriate for young learners and incorporates activities adaptable to virtual learning (e.g., drawing pictures and going for a scavenger hunt near one's home). The sixth link brings readers to an entire unit of materials on "Molecular Genetics and Heredity of Livestock," curated by Sam Houston State University. These materials are more appropriate for older learners (high school and beyond). |
