The author hypothesizes that the heating up of the squirrel’s tail probably helps to repel rattlesnakes. This is based on the fact that adult squirrels harass threatening rattlesnakes by wagging and puffing up their tails. In addition, the tail heats up, and rattlesnakes can detect body heat.

The author assumes there isn’t another explanation for why the squirrel’s tail heats up when a squirrel harasses a rattlesnake.

We’re talking about the purpose of squirrels heating up their own tails. Rattlesnake tails are irrelevant.

This has no clear connection to the heating up of a tail and whether it’s related to repelling rattlesnakes.

This strengthens the hypothesis by making it more plausible. The heating in a squirrel’s tail seems to make the rattlesnake feel more threatened, which is what we’d expect if the heat played a role in repelling snakes.

The argument is about the role of a heated tail in repelling rattlesnakes. Other predators don’t strengthen the connection between a heated tail and repelling rattlesnakes.

We’re talking about the effect of a squirrel’s heated tail on rattlesnakes. Whether squirrels can detect heat doesn’t matter, because we know that rattlesnakes can detect heat.
