[Solved] We can't detect stellar parallax with naked- eye observations. Which of the following would make parallax easier to observe? A)slowing down Earth's orbital motion B)increasing the size of Earth's orbit C)Speeding up the precession of Earth's axis D)speeding up Earth's orbital motion E)getting away from streetlights Group Selection: A theory in evolutionary biology proposing that natural selection operates on groups or populations, favoring traits that benefit the group as opposed to the individual. Gene-Centered View: A perspective in evolutionary biology that focuses on the role of genes in driving the process of evolution through the survival and replication of those genes that confer a selective advantage. Evolution by Natural Selection: A process where organisms better adapted to their environment tend to survive and produce more offspring, leading to the prevalence of beneficial traits in a population over generations. Gene Frequency: The ratio of a particular allele to the total of all other alleles of the same gene in a given population.
