If the Earth were under the action of tidal capture, then there would be intense heat on one side, and intense cold on the other. In either case, the existence of higher forms of protein life would be impossible. Nevertheless, in the twilight zone, as shown in another answer, the temperature would be average, i.e. acceptable.
Also in this case, strong air currents would be observed. In the case of a temperature drop, there is always a pressure drop that causes wind. It, in turn, causes temperature equalization. Creatures living in the twilight zone would have evolved and, in order not to become blown away by the wind, would have become very heavy and with long prehensile claws. Well, that is, they would be unlike us.
