**4. Step-like Solutions of the Equation with Two Delays**

We normalize the time *<sup>t</sup>* → *Tt* and rename *<sup>λ</sup><sup>T</sup>* as *<sup>λ</sup>* and *hT*−<sup>1</sup> as *<sup>h</sup>* (*<sup>h</sup>* < <sup>1</sup>) again in Equation (8) with two delays. As a result, we arrive at the equation

$$
\dot{u} = \lambda \left[ 1 - \kappa u(t - 1) - (1 - a)u(t - h) \right] u(A - u). \tag{37}
