Evolution of the Primate Brain: What Makes Us Human?

Darwin’s famous voyage to the Galapagos Islands in 1831 formed the foundation of the theory of evolution [1]. Since then, scientists have applied this theory to investigate the diversity and relationship between species. Although Darwin’s theory of evolution states that humans evolved from primates, the definition of cognitive function and consciousness was not explained clearly. According to the Cambridge Declaration …

Evo Devo and the Mechanism of Evolution

Evolution, in the macroscopic sense, has probably been explained to you time and time again in your science classes as tiny changes that over time build up and create differences among species. From a single common ancestor, different species evolve, eventually creating the huge diversity of life we see today. But have you ever considered how that change comes about? …

Robbing Peter to Pay Paul: The Evolutionary Trade-Offs of Hemochromatosis

Given Darwinian principles of natural selection, it might seem unusual that genes coding for hemochromatosis persist in humans. Hemochromatosis is a disease that causes excess iron to accumulate in cells, tissues, and bloodstream. Untreated, hemochromatosis leads to premature death. It is unlikely that a gene with such detrimental effects would exist without some benefit for humans; therefore, there must be …

The Internet to Attain State of Consciousness: An Actuality or Improbability?

“The internet is a new lifeform that shows the first signs of intelligence.” -Jeff Stibel, a neuroscientist and entrepreneur [1]. The notion regarding the Internet’s potential of undergoing evolutionary processes and attaining the coveted state of consciousness revolves primarily around two main concepts: the definition of consciousness amongst the different entities that seem to possess it, and the establishment of …

Is the American Stance on Evolution Evolving?

The theory of evolution faced a strong backlash in the very beginning. In fact, Charles Darwin did not even venture near the topic of human evolution when he initially published his now famous On the Origin of Species. Then, he faced the threat of religious disapproval in 19th century England, but hundreds of years later, is the United States, a …

Epigenetics: In Defense of Lamarck

Jean-Baptiste Lamarck has long been debunked. Or so the story goes. Lamarck formulated the theory that the environment shapes genes, and that these changes are passed on to your children; on other hand, Darwin argued that genes are not changed by the environment and formulated natural selection. Lamarckian evolution theories on environmentally acquired characteristics are often referenced and contrasted with …
