Evolution and Judaism: What Has Science Really Proven About Evolution?

What exactly has and has not been scientifically proven regarding evolution? This is a broad question, but my main concern is how to understand the Torah’s account of Creation in Parashat Bereishit. I assume (though I may be mistaken) that some aspects of evolutionary theory have been demonstrated. For example, dinosaurs seem to be well established (although their existence is not necessarily a contradiction to religion). I would like to know which parts of evolutionary theory have actually been proven. Is it possible that there is an evolutionary process in which one species splits into several species — not a mammal becoming a bird, but perhaps a deer population dividing into two distinct species? And so on.

Please excuse the lack of precision in my question, but I believe the general idea is clear. Thank you in advance.

Hello and blessings,

Dinosaurs actually pose significant challenges for evolutionary theory. According to this view, they appear in the fossil record without clear evolutionary predecessors, and their extinction remains a major question, especially since many mammal species survived. The nineteenth-century commentator Malbim wrote that the giant creatures that lived before the Flood perished during the Flood itself.

Our Sages taught that a falsehood cannot endure unless it contains some element of truth.

Evolution, according to this perspective, is not viewed as a complete falsehood, but rather as a theory that mixes truth with error. For example, even the Talmud recognizes that species can undergo change — but not in the sense that one type of creature transforms entirely into a different kind of creature. Changes occur within the boundaries of a species.

This can be seen in the diversity among human beings: people with different skin colors, facial features, and other characteristics. The Zohar explains that living creatures adapt to their climate and environment. However, these changes are already encoded within the organism’s genetic potential; they do not represent the creation of entirely new forms of life.

The Talmud even describes a type of bird that diversified into many different varieties. Yet all of them remained birds.

As you noted, differences such as skin color and other physical traits are influenced by climate. The Zohar teaches that G-d created living beings with the capacity to adjust to environmental conditions. From Adam and Eve ultimately came Asians, Africans, Europeans, and all the peoples of the world.

It is important to understand that these external changes are not considered “evolution” in the sense of creating new life forms. Rather, they reflect characteristics that were already present within the genetic makeup of humanity. Even your own descendants, if they were to live for many generations in regions with intense ultraviolet radiation, would likely develop darker skin over time.

I would be happy to answer any further questions.

With blessings,

Daniel Blass
