Rudimentary organs and evolution

In his text, Evolution, Genetics, and Man, Dobzhansky wrote, "There is, indeed, no doubt that vestigial rudimentary organs silently proclaim the fact of evolution." III.

Darwin defines vestigial structures as structures that persist within a species but have lost their function. In the context of human evolution, human vestigiality involves those traits occurring in humans that have lost all or most of their original function through evolution.

2020-01-02 · Some organs are referred to as “vestigial” because they are assumed to be a “vestige”—a leftover—from an earlier evolutionary form. The term vestigial implies a lack of use, purpose, or function. Common examples in human beings of “vestigial” organs are the appendix, the tailbone, and nipples on males.

Darwin on “Rudimentary Organs” Darwin speculated that these rudimentary organs once served a function necessary for survival, but over time that function became either diminished or nonexistent. Charles Darwin was perhaps the first to claim vestigial organs as evidence for evolution.

The Compact Oxford English Dictionary defines the word vestigial as: “(of an organ or part of the body) degenerate, rudimentary, or atrophied, having lost its function in the course of evolution.” The origin of complex biological structures has long been a subject of interest and debate. Two centuries ago, natural explanations for their occurrence were considered inconceivable. However, 150 years of scientific investigation have yielded a conceptual framework, abundant data, and a range of analytical tools capable of addressing this question. This article reviews the various direct and Charles Darwin pointed to these vestiges of anatomy in humans and other animals as evidence for evolution.Eventually, by noting how the vestigial organs in one species were similar to functioning V estigial organs are rudimentary anatomical. and social characters hypothesized to drive appendix evolution for 533 mammalian species.
