Design in Crane Fly Eyes
Fossilized crane fly eyes discovered to be calcified and have melanin
Cnidarians appear to have recruited as toxins the same kinds of proteins recruited by many other venomous animals. However, toxin diversity within groups of organisms does not appear to be related to the alleged evolutionary history of the various groups.
The specific genes have been identified that cause a lizard to match the black rocks it lives on.
Is the genetic basis of loss of flight due to mutations in protein-coding genes or in regulatory genes?
Comparison of genomes of jellyfish and sea anemones highlights the importance of orphan genes in taxonomically close organisms.
Different populations of stickleback fish have parallel genetic adaptations to similar local habitats.
A jumping spider has been discovered to produce a kind of milk to nourish its babies, in a manner similar to what mammals do.
Hybridization among wood warblers suggests “filling the earth” through dispersal, speciation and adaptation to local habitats.
In recent decades, epigenetics has been shown to be a promising field of research, since it describes changes in inheritance patterns that do not involve DNA modifications and are related to interactions between the organism and the environment. Epigenetic marks are chemical changes that occur in chromosomes and result in the silencing or activation of specific genes in different tissues. It has been…
During one of my frequent visits to the office of my high school headmaster, his individual tutelage yielded a life lesson that I’ve never forgotten. His exact words were, “You think you’re right!” Of course I thought I was right, wouldn’t anyone who thought they were wrong change their mind and then immediately think they are right? Now that I’m an adult biologist, I still think that I’m right. Inevitably…
Most nature documentaries include some language that refers to an underlying naturalistic understanding of origins. However, the recently released nature documentary “The Riot and the Dance” breaks this common pattern in a refreshing way.
One person’s cultural background can bias their view about people from other cultures… even before they have ever met. Could people also have a bias about how they think about other creatures? It may even be possible that scientific culture could prejudice the way researchers see creature-environmental relations with the potential to bias whole research programs.
A very common reaction to the thought of “microbes” is a compelling desire to slather up in hand sanitizer! However, it is seldom realized that the greatest majority of microorganisms are at the very least not harmful, and at the most necessary for human life! Many aspects of microbial interaction with our environment allow it to be so perfect for humans. Some of these aspects include oxygen generation,…
The number of different kinds of living organisms is one measure of biological diversity, or what has become known as “biodiversity.” Our world’s oceans have the highest known biodiversity, second only to the number of species found in the tropical rainforest.
The third part of this series on biogeography examines how the flood might have influenced the present patterns of distributions of various types of living organisms.
The West Chester University Professor of Biology, Frank E. Fish, was vacationing along New England's coast frequented by magnificent humpbacked whales. While browsing in a gift shop one day he couldn't help but notice a gifted sculptor’s rendition of one of the splendid creatures and commented to the shop owner that the artist had put bumps on the wrong side of the pectoral fin. The bumps should be…
What is the utility of a fourth or a fifth of a wing stroke? Could any insect or bird get by with a wing that is a fraction of its normal size? Could it serve its purpose working at a reduced capacity? These questions are a challenge for those who accept Darwinian gradualism and adaptation. According to the Darwinian evolution theory, biological traits arise by small genetic variations steadily modifying…
Recently I flew to London on the new Boeing 787 Dreamliner. Despite what media hype might lead a Dreamliner passenger to expect, there were no fires on board and the experience wasn’t particularly different from what I’ve experienced on innumerable other flights. From my perspective, the seats were too small, too close together and too hard. That is not to say that there were not some differences,…
The idea that different types of organisms were created and commanded to reproduce "after their kinds" seems widely believed among creationists. It may therefore come as a surprise to many to learn the idea is not stated in the Bible.
