In scientific terms, we could say that the bat, the bird, and humans have homologous structures. This means that limbs have similar bone structures like the ones shown in the picture. Being the anatomy so similar, scientist concludes that some animals descend from the same ancestor in the process of evolution. So if we trace back these ancestors, we could find that we have similar origins.
