Evolution - BIOL520

Evolution is the process in which organisms change or adapt to better fit their environment and/or cohabitate/survive with the other organisms in their environment. I add the second part because organisms can evolve together. Last semester I took Organismic Biology, and I learned that moths and bats constantly evolve to outwit one another -- moths to stop bats from eating them, and bats to keep being able to eat the moths. Bats have developed echolocation to be able to find moths in the darkness of night. The echolocation sends sound pulses which bounce off objects/organisms and allow the bat to determine what the sound waves hit and its position. Moths came up with the ability to emit their own sonar to either block the bat’s waves or confuse it, and some moths developed the ability to send sounds that signaled that they were poisonous or would taste bad. This is an example of behavioral evolution, and the moths and bats have coevolved. Here is a link to a youtube video with more i...

 I'm Erin Jones. I'm a senior majoring in Biology, and I'm from Abilene, Kansas. I'm passionate about cats, elephants, and Greek mythology. My top Spotify songs last year were a mix of Beyoncé, songs from Little Shop of Horrors, and other random movie soundtracks.  I decided to study biology because I find the complex processes required to create and sustain life to be really amazing, and I wanted to learn more about them.  My mom studied biology, too, and one thing that she's told me that has stuck with me is that everything changes. If you stop changing, you die -- her words, not mine. As the world changes, as environments and organisms change, evolution is necessary for life to keep living. Also,  I have recently heard of the concept of carcinisation, which is the tendency of organisms to evolve into crabs. I have not heard much past that, so it would be cool if that was a topic we discussed.  I don't think evolution necessarily relates to daily lif...
