For years, researchers have relied on the same theory on how tigers got their stripes. However, science is not so certain anymore that these theories are correct.   

The morphogen theory states that proteins controlling traits are arranged as gradients, with different amounts of proteins activating genes to create specified physical features.

This theory first evolved in the 1950’s by World War II mathematician and was refined in the 1960’s. Ever since, it has been the theory that has been used to explain why tigers have their stripes and where they come from. 

Now, some biologists are raising questions about the theory and believe that physical features are necessarily tied to absolute concentrations of proteins within the morphogen gradient.

Contrary to the theory’s surfacing in the 1950’s and 60’s, researchers have recently found that a single gradient lf proteins does not have sufficient power to from the same body plan in each member of a species. Nevertheless, if there are multiple gradients working against each other, then the system becomes robust enough for normal development.

So, the question still remains: How Did Tigers Get Their Stripes? What theory do you believe? Let us know on the AllPet Facebook Wall, linked HERE.
