Bonobos, Chimpanzees, and the 98% DNA Link
|
view preview
When it comes to the animal kingdom, we often find ourselves marveling at the diversity of species that inhabit our planet. Regardless of our differences, the more we delve into the intricacies of genetics and biology, the more we realize just how interconnected all life on Earth truly is. One remarkable example of this interconnectedness is the relationship between humans, bonobos, and chimpanzees. Despite the differences in their "personality" traits, our DNA tells a compelling story of our shared ancestry with these incredible primates. Bonobos and chimpanzees, our closest living relatives in the animal kingdom, are often viewed as two sides of the same evolutionary coin. While they share approximately 98 percent of their DNA with each ot ...

Birthmarks and what causes them
|
view preview
Birthmarks are congenital marks on the skin that appear at birth and occasionally disappears spontaneously. The term nevus refers to a benign cutaneous tumor consisting of blood capillaries. Such tumors, which rarely spread from their original site and are not dangerous, vary in color according to whether the capillaries composing them carry arterial or venous blood. The popularly termed cherry marks and port-wine stains (shown below) are nevi on a level with the surface of the skin. Certain other vascular nevi, commonly known as strawberry or raspberry marks (scientifically known as hemangiomas), are slightly elevated above the surface. These can appear anywhere on the body's surface, including the airway within the nose. The former Soviet ...

Why do archaeologists and geneticists reach different conclusions?
|
view preview
An archaeologists is a scientist who studies human history by discovering and examining human remains and artifacts. The most common image of an archaeologists is someone on their hand and knees digging through dirt, carefully using a brush to dust off an artifact from the distant past. A geneticist, on the other hand, is someone who specializes in the science of genetics. This field of biology deals with the pattern of inheritance, molecular structure and function of genes, and gene behavior in context of a cell or organism. Both professionals are highly skilled, and use the same basic principles of science to test hypotheses, gather data, and make conclusions. However, why do archaeologists and geneticists sometimes reach different conclu ...
