Neanderthal and Homo Sapien DNA: What does it indicate?

Past posts have described the science of evolution, and the development on Earth over time of its atmosphere and of various life forms. Prior posts have also noted that science is a constantly changing picture as new data and information are developed. Speaking of recent developments, research now appears...

The foundations of life may have formed in cold environments, not hot or temperant

The scientific debate over the origins of life have found support for molecular formation and replication in boiling hot deep-sea hydrothermal vents and volcanic hot springs, as well as the warm little ponds postulated by Darwin. Now comes evidence for the other end of the temperature spectrum, the very...

Seaweed and licorice may help improve the immune system of swine, decreasing the need for antibiotics

As noted in prior posts, antibiotics are used not only to treat disease in animals, but also to prevent disease and to stimulate growth. Unfortunately, but not surprisingly, the use of antibiotics in animal husbandry has lead to the rapid development of bacteria that are resistant to such antibiotics...

The Columbian and Woolly Mammoth may be one highly variable species

What is interesting about genetic analysis is the way it has the potential to upset otherwise well-established classifications of animals. A good example is the Mammoth, Ice Age beasts well known to one and all. Although they both roamed North America a millennia ago, accepted taxonomy had classified...

Evolutionary Change Is Just That, Change, and Change Often Is a Mixed Bag and More Complex Than Anticipated

There is an unfortunate tendency to conceive of evolutionary change as causing an adaption to a selection factor that marks an improvement in addressing the environment in which the selection factor exists. Were it only so simple. Change may be an improvement, but sometimes it brings unfortunate baggage...

More Studies are Focusing on the Types of Bacteria that are Part of all Humans

Prior posts have noted that a) for every 1 human cell there are 10 bacteria in or on our bodies; b) these bacteria are key to the digestion of our food, production of necessary nutrients, and disease prevention; c) the nature of our diet influences the make-up of bacterial colonies in our GI tract; d...

What is the genetic mechanism that drives evolution? Perhaps we have been looking in the wrong place.

Prior posts have noted how in the recent past the perceived wisdom was the 1% of the human genome was responsible for what happens (the making of proteins), and the balance (99%) was "junk." Over time the amount deemed relevant has grown and the junk portion has shrunk. Recently the ENCODE...

Do comb jellies indicate that evolutionary theory needs a serious rethink? Maybe instead they are a door to understanding the evolution of complexity

When viewing evolution over time, scientists generally favor parsimony, that is, lineages radiating from a common ancestor share most of the ancestor's features. This also means that animals at the bottom have simple features, which may grow more complex or which may become more specialized as other...
