Genotypes and Phenotypes

Phenotype is the outside characteristics that is changed by genotype and affects the survival of the species involved. Selection acts on phenotype to produce evolutionary change as it is what affects the survival of the specifies involved. If it is a beneficial phenotype that increases survival rate, it will then increase the reproduction rate of that species that will produce evolutionary change as the members of the species with the beneficial phenotype will outlast those without the beneficial phenotype, thus producing more offspring with the genotype for the beneficial phenotype.

Convergence, Natural Selection, 'Survival of the Fittest'

1.) A great example of convergence from the "Improbably Destinies" Chapter 1 was the example of caffeine-producing species. 2.) Convergent evolution is when multiple species have similar traits but do not have a common ancestor. The multiple species independently evolve these similar traits. Divergent evolution is quite the opposite of convergent evolution. Divergent evolution is when related species have evolved similar traits, while convergent evolution is for species who have evolved similar traits and do not have a common ancestor. 3.) The example in #1 showcases convergent evolution because it talks of how these multiple species, cacao, tea, and coffee all produce caffeine but they are on different branches of the evolutionary tree as the diagram below shows. This shows that these species, cacao, tea, and coffee all evolved the caffeine-producing trait independently from one another.  4.) Due to natural selection, these species could have developed convergent features be...

Sexual Selection

Image
Sexual selection typically acts on males of the species due to male-to-male competition. I learned a lot in our in-class activity about sexual selection, especially with the comic strip we went over. I didn't think there could be a variation of successful mating strategies, it just depended on the situation! I would like to further explore the topic of female choice in sexual selection.
