My point about fear was that both mammals and reptiles exhibit the recoil-from-immediate-threat response, and share the same neurobiological substrate for it. To that extent, reptiles have emotions. No, they can't feel fear about the future. But I would have the recoil-from-immediate-threat response if I nearly stepped on a diamondback, and the diamondback would too! LOL.
Absolutely, ALL animals exhibit fear as an instinctual response to immediate danger. It's absolutely a biological instinct.
It is, however, very different from our personally realized, self-created fears, which are emotional responses to our own cognitive processes. These emotional fears which are based on self-created and percieved threats, rather than actual stimuli, are the emotional fears that animals do not have the capacity for, according to all the major research currently available in the scientific world...except for a book or two...
