Darwinism
Darwinism, the theory of the evolutionary mechanism propounded by Charles Darwin as an explanation of the organic change. It denotes Darwin’s specific view that evolution is driven mainly by natural selection. Read more
What is Darwin’s Theory of Evolution?
The Theory of Evolution by natural selection was first formulated in Charles Darwin’s book “On the Origin of Species” published in 1859. In his book, Darwin describes how organisms evolve over generations through the inheritance of physical or behavioral traits, as National Geographic explains. The theory starts with the premise that within a population, there is variation …
What are Darwin’s Four Main Ideas on Evolution
English Naturalist Charles Darwin used his keen observation skills and logic to develop a comprehensive theory that describes the process of evolution. While some controversy surrounds evolution as it applies to human populations, Darwin’s theory applies to all organic species. The basic principles of evolution are simple and seem obvious to the modern reader. However, …
Adam Smith
Adam Smith is often identified as the father of modern capitalism. While accurate to some extent, this description is both overly simplistic and dangerously misleading. On the one hand, it is true that very few individual books have had as much impact as his An Inquiry into the Nature and Causes of the Wealth of Nations. …
The Future is Mixed-Race And so is the past. Migration and mingling are essential to human success in the past, the present and into the future
In the future, a lot of people might look like Danielle Shewmake, a 21-year-old college student from Fort Worth, Texas. Shewmake has dark, curly hair, brown eyes, and an olive skin tone that causes many to mistake her heritage as Mediterranean. Her actual pedigree is more complex. Her father is half-Cherokee and half-Caucasian, and her …
What is Natural Selection?
Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time. Natural selection is one of the ways to account for the millions of species that have …

Culture drives human evolution more than genetics
Researchers found that culture helps humans adapt to their environment and overcome challenges better and faster than genetics. Tim Waring and Zach Wood found that humans are experiencing a ‘special evolutionary transition’ in which the importance of culture is surpassing the value of genes as the primary driver of human evolution. Due to the group-orientated …
The fundamentals of cultural adaptation: implications for human adaptation
The process of human adaptation to novel environments is a uniquely complex interplay between cultural and genetic changes. However, mechanistically, we understand little about these processes. To begin to untangle these threads of human adaptation we use mathematical models to describe and investigate cultural selective sweeps. We show that cultural sweeps differ in important ways …
Cultural evolutionary theory: How culture evolves and why it matters
Human cultural traits—behaviors, ideas, and technologies that can be learned from other individuals—can exhibit complex patterns of transmission and evolution, and researchers have developed theoretical models, both verbal and mathematical, to facilitate our understanding of these patterns. Many of the first quantitative models of cultural evolution were modified from existing concepts in theoretical population genetics …
