It is one of the most dynamic fields of study in all of biology. Over the last several decades, new research has challenged scientists’ ideas about how organisms are related. New models of these relationships have been proposed for consideration by the scientific community.

However, it is not the absolute fitness of an individual that counts, but rather how it compares to the other organisms in the population. This concept, called relative fitness, allows researchers to determine which individuals are contributing additional offspring to the next generation, and thus, how the population might evolve.

It highlights how sexual reproduction fosters genetic variation through the fusion of sex cells and meiosis, which reduces chromosome numbers. While asexual reproduction may allow for quicker population growth, sexual reproduction prevails in multicellular organisms due to its evolutionary advantages linked to genetic diversity.

It highlights the role of mutations in evolution, gene duplication, and translocations, along with their rarity and varying rates across species. Specifically, C. elegans has a mutation rate of approximately 2.1 x 10^-8 per base pair per generation, with males contributing more due to mitotic divisions.

Students engage in lab exercises that include flower dissection and explore various fruit types, including seedless varieties and classifications of dry fruits. The significance of seed dispersal mechanisms and genetic diversity through pollination methods is highlighted, along with practical aspects of embryonic development and germination.

That species change had been suggested and debated well before Darwin began to explore this idea. The view that species were static and unchanging was grounded in the writings of Plato, yet there were also ancient Greeks who expressed evolutionary ideas.
