  1. There were small insectivores that were bipedal, but they died due to environmental factors. It's possible that, given the chance, they could have evolved into bipedal carnivores.

  2. It's likely a combination of various factors. Long necks may have initially evolved due to sexual selection, but then would have become more viable for natural selection due to their other benefits such as opening up new niches.

  3. Well technically they didn't get their necks by stretching for foods. They got their long necks due to either natural or sexual selection. Giraffes with longer necks tended to have a better chance at surviving and reproducing, leading to the modern day.
