Related to his work on logic in particular, Aristotle has had a profound influence on the sciences. While this includes his ideas of deduction and induction, he also heavily emphasized the ideas of empirical research or observation. While earlier scientific philosophers were more theoretical and less observation oriented, Aristotle tried to make observations around him, including organizing trips to places, such as Lesbos, or dissecting animals to understand how they functioned. For instance, he observed that dolphins are not fish more similar to land animals.<ref> For more on Aristotle's approaches to science, see: Leroi, A. M.

His classifications were based on shared features, which is more similar to our form of classification. He successfully identified more than 600 species of wildlife. <ref> For more on Aristotle's contribution to Biology, see: Lennox, J. G.

Cambridge, UK ; New York: Cambridge University Press.</ref> Aristotle also noted how geological features are changing and they are difficult to observe because the timescales are often longer than human life. However, by noting that lakes and land forms are constantly changing, these ideas do influence famous geologists such as Charles Lyle, who ultimately helped develop modern geology.<ref> For more on Aristotle's contribution to Geology, see: Green, J.

Aristotle also tried to created a theoretical foundation in areas such as sleep, psychology, physics, astronomy, and other fields. Often, his views were wrong, but that often had to do with the fact he lacked means to properly observe events.<ref>For more on areas Aristotle impacted, see: Byrne, P. H. (1997). <i>[https://www.amazon.com/gp/product/0791433226/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=0791433226&linkCode=as2&tag=dailyh0c-20&linkId=dba4e50f39931077a6d70d99f0f6e0c9 Analysis and science in Aristotle]</i>. Albany: State University of New York Press.</ref> Nevertheless, because Aristotle's ideas were so influential, many of his concepts were adopted and held for centuries or even millennia. For instance, his belief that the Earth was the center of the universe was eventually adopted as a core belief by the Catholic church. Thus, his ideas also began to be adopted by later religious authorities.
