How can physiology be used as evidence of evolution?

Physiology can provide evidence of evolution by showing how certain traits or adaptations have evolved over time to enhance survival and reproduction. For example, studies on the physiological differences between closely related species can reveal how changes in gene expression or protein function have allowed for adaptation to different environments. By comparing physiological traits across different species, scientists can infer evolutionary relationships and the processes that have shaped them.


What is the significance of cytotaxonomy over physiological taxonomy?

Cytotaxonomy uses the study of cell structure and chromosome numbers to classify organisms, providing insights into evolutionary relationships. This is significant because it can reveal genetic differences that may not be apparent through physiological traits, leading to a more accurate classification of organisms. Physiological taxonomy, on the other hand, relies on observable physiological characteristics, which can sometimes be influenced by environmental factors and may not fully reflect genetic relatedness.
