Evolution of Walking

Evolution of Walking

Autumn Lee, Journalist

Scientist have often wondered about the wiring that allowed animals to walk. Now they know, with a recent study on cartilaginous fish called Little skates. Genetic evidence has proven that land vertebrates and little skates share a similar genetic makeup. On February 8 an online analysis concerning the relationship of the species was published titled in Cell. This research is the first to take a gander at the inceptions of the neural hardware required for walking.

Scientist and author of Cell have realized the connections between us and these unique fish. Little skates operate in moving in a similar fashion that humans do. They Little skates utilize two foot-like balances on their undersides to move along the sea depths. With an exchanging left-right walk controlled by muscles flexing and broadening, the development of these fish looks a considerable measure like that of numerous land-based creatures. Many scientists involved with this research found it very surprising to find these connections to common ancestor. Scientist at New York University estimate that this ancestor of lived about 420 million years ago. Although, Little skates have since evolved from their ancestors they still share characteristics such as a straight spine, similar neural circuitry, and a movement that mimics walking on feet.  Most fish swim by undulating their bodies and tails.

The takeaway of this research is that “vertebrates are for the most part fundamentally the same as each other.” Discovering this similarity has broadened a wide range of research and discoveries in the scientific community.
