How and why would an organism evolve BioSteel?

BioSteel is a substance produced by goats whose DNA has received the silk-producing genes of spiders.

While silkworms are generally social creatures, spiders are reclusive, meaning they cannot be farmed effectively for their strong silk. However, when silk-producing chemicals can be made "naturally" by a goat, and excreted through its milk, the silk can be farmed easily. It is estimated a single goat is capable of generating enough silk in a day to spin 34,000 meters of BioSteel thread.

When refined, BioSteel is incredibly strong, compared to more common metal alloys, such as steel, whilst still retaining a remarkably high flexibility and durability.

But how and why would something evolve, naturally, to produce so much of this substance?
