They had bulging jaw muscles and serrated mouthparts. They were very aggressive and ate much bigger food than normal.

Even from a behavioral standpoint, we are nowhere near similar; humans have developed an interpersonal societal web of interaction of unprecedented magnitude in comparison to other animal species across the entirety of recorded life on earth. However, these two drastically different animals share one similarity that is nothing short of shocking: conscious, associative memories.

Three Terms Essential to Biology

I am choosing words that are important to understanding certain biological concepts, but also selecting words that sparked my interest and intrigued me the most to continue learning biology. The three terms or phrases I will be focusing on in this blog are genetics, natural selection, and DNA.

How Can Parasitic Worms Enhance the Ecosystem?

Nematodes which live inside horned passalus beetles which can benefits both of them. Although Nematodes are parasitic and they feed of on the beetles’ hemolymph, which is basically the insects’ blood, and will eventually suck up all of the beetles available energy and kill them. Whether this relationship is harmful or mutualistic is still a question?
