The Common Descent Podcast: Sexual Selection

 One thing that I did not understand completely from the podcast was the difference between the types of condition dependent indicator and the condition independent indicator. 

It was said that the condition dependent indicator is when a female chooses a male that has survived to reproductive age so the male will pass those those traits that made him survive to the females young so her young will then be able to survive. 

The condition independent indicator was said to be traits directly linked to a genetic benefit. 

I am needing more information on the condition independent indicator because I am not sure how the female is able to pick out those traits. 

One thing that I found to be new information to me and to also be interesting was "Sexy Sun Model". This model states that there is no benefits to the traits that the females like, the females just like these traits for random reasons and this causes a feedback loop where more of the traits are in the environment overtime.

    Hi Aubree! I was confused as well about the condition dependent/independent indicator. The way you explained it from the podcast is equal to my understanding about the subject but I am unsure as well how the females are able to pick out those traits!!

    Hi Aubree, what I understood from the podcast was the feature tells the female that the male is more fit in the condition-dependent indicator, so I'm guessing there is something about the trait that the female sees as useful, but I don't know exactly how the female picks out the trait.

    Hey Aubree!!!
    From my understanding on the topic, this specific trait indicator simply tells the female which male has the better fitness and could be more useful for the female. She then chooses based on that. Great Job!!

  This is my Final Project !

Phenotypic Plasticity

 Phenotypic Plasticity is the ability of an organism to change their phenotype in relation to the environment that they are in.  In the paper " The Genetic Basis of Adaptation following Plastic Changes in Coloration in a Novel Environment"  a study was done on lizards that live on these lava rocks. The lizards living on the dark lava rocks have a dark phenotype that enables them to blend into the rocks. These researches found that when you remove these lizards from the dark rocks and place them on a much lighter substrate, then these lizards become much lighter in color in order to blend in with the substrate. They also compared the lizards already living on the lava rocks to lizards nearby who were living off of the lava rocks. They found that when exposed to the dark colored substrate that both groups of lizards had a much darker phenotype, however, the researchers observed that the lizards already living on the lava rocks had darker phenot...
