post 1 ecolocation

 human ecolocation is one of the first things that the book brings up and its pretty interesting stuff.  One of the main things that caught my eye was that Normal people can use this same skill and don't need a whole lot of practice to use it. The book talks about the people already use sound to figure out there surrounding and it talks about bats doing it as well. One of the interesting thing about bats is this https://www.usgs.gov/faqs/are-bats-blind?qt-news_science_products=0# Bats are actually able to see. They just use sound to help them just like we use sound to help navigate around. Its something interesting to think about. Justin c
