The Intersection of Physics and Darwin's Evolutionary Theory
Written on
Chapter 1: Darwin’s Revolutionary Idea
Charles Darwin stands as a pivotal figure in 19th-century science, credited with developing the foundational theory of evolution, which explains the origins of biological species. Yet, during his lifetime, significant challenges emerged, suggesting that physicists had successfully undermined his theory.
The Flaws in Darwin's Evolutionary Theory
One major critique came from British physicist Lord Kelvin, who identified a critical flaw in Darwin's hypothesis—specifically, the pace of natural selection. The process of biological evolution through natural selection is exceedingly gradual, necessitating vast expanses of time for new species to evolve.
By the time Darwin was formulating his ideas, paleontology was gaining momentum, revealing numerous fossilized species that existed alongside contemporary life forms. This indicated that hundreds of millions of years of evolutionary processes were needed for such diversity to arise.
Kelvin’s Earth Age Calculations
Kelvin, leveraging knowledge about the Earth's temperature gradient, understood that the planet's core was a heat source, gradually cooling over time. He based his age estimations on the melting point of rock and the rate of cooling, leading him to conclude between 1861 and 1897 that the Earth was around 20 million years old.
These findings cast doubt on Darwin's theory, as 20 million years seemed insufficient for the emergence of a diverse array of species through natural selection—especially since the Earth's surface was likely too inhospitable for life during its early years.
Simultaneously, in 1853, German physicist Hermann von Helmholtz estimated the Sun's age at around 18 million years, further complicating Darwin's timeline. Additionally, in 1899, physicist John Joly calculated the Earth's age based on ocean salt accumulation, arriving at a figure between 90 and 100 million years, still seen as inadequate by Darwin's standards.
Darwin's Counterarguments
In response, Darwin attempted to challenge these figures, suggesting that chalk deposits in southern England could be at least 300 million years old due to erosion. However, his calculations were met with skepticism and ultimately dismissed by the scientific community. He later retracted these findings in later editions of "On the Origin of Species."
Transformations in Scientific Understanding
The landscape of evolutionary theory shifted with a new generation of physicists—Henri Becquerel, Pierre, and Marie Curie—whose groundbreaking discoveries in radioactivity rendered Kelvin's earlier calculations obsolete.
These scientists revealed that radioactive elements generate heat that Kelvin's calculations failed to consider. By evaluating the abundance of uranium and other isotopes in the Earth's crust, they were able to estimate the Earth's age in the billions of years. Tragically, Darwin did not live to witness this pivotal advancement.
As the 20th century unfolded, the discovery of nuclear fusion illuminated the Sun's mechanisms for generating heat and light, allowing for a more accurate assessment of its age.
Consequently, the notion of a "young Earth," frequently cited by Darwin's detractors, was dismissed as lacking substantial evidence.
