Jurassic Park Theme

I am listening to "Black Banjo Songsters of North Carolina and Virginia" and noticed that track number 1: "Coo Coo" by John Snipes is very similar to "Theme from Jurassic Park" by John Williams. By very similar I mean the similarity is greater than that between Solomon Linda's "Mbube" and The Tokens' "The Lion Sleeps Tonight." I don't really know what to think of this, but I felt that I should record it.
