  • HDMI isn’t necessary for HDCP though. HDCP also works over DisplayPort and even DVI.

    Edit: The HDMI article on Wikipedia that you linked even says:

    The HDMI founders began development on HDMI 1.0 on April 16, 2002, with the goal of creating an AV connector that was backward-compatible with DVI. At the time, DVI-HDCP (DVI with HDCP) and DVI-HDTV (DVI-HDCP using the CEA-861-B video standard) were being used on HDTVs. HDMI 1.0 was designed to improve on DVI-HDTV by using a smaller connector and adding audio capability and enhanced Y′CBCR capability and consumer electronics control functions.









  • We don’t know whether they evolved these chemicals to prevent being eaten by animals though. People have tested spicy (capsaicin based) foods with mice, and found that mice actually seemed to like or not really react to spicy foods. This means that capsaicin did not evolve to protect against rodents like initially thought.

    In fact, we now know that capsaicin is a very powerful antifungal chemical. Chili peppers naturally grow in hot, humid environments where fungi thrive. There also aren’t many rodents in those areas. So the spiciness experienced by mammals like humans is just a side effect that didn’t really affect its evolution.
