The two-experiment performed by a scientist with a forelimb mesenchyme and seeing their results;

I-leg mesenchyme is placed directly beneath the wing AER

II-limb mesenchyme is replaced by non-limb mesenchyme beneath the AER

Conclusion of these experiment are seeing; 

a) distal hindlimb structures develop at the end of the limb

b) supernumerary structures are formed, usually toward the distal end of the limb

c) the AER regresses and limb development ceases
