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.

Is a recent fossil found in Peru evidence for transitional forms in an evolutionary sequence?

Different populations of stickleback fish have parallel genetic adaptations to similar local habitats.

Hybridization among wood warblers suggests “filling the earth” through dispersal, speciation and adaptation to local habitats.

Much effort has been expended in attempts to arrange living organisms in a pattern based on genealogy. However, a tree-like pattern is not as evident as evolutionary theory would predict.

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…

A fossil bird recovered from Cretaceous lake deposits in China shows preservation of some soft tissues, including a pair of lungs that appear to have functioned in a way similar to those of living birds.

A living being is more than the collection of the multitude of organic components of which it is made.

EDITORIAL. Those who study historical topics such as origins often face questions for which no easy answers are evident. Nevertheless, there are some things that can be known, and these should not be overlooked. Published in Origins, n. 65.

A review of the book, Theistic Evolution: A Scientific, Philosophical and Theological Critique. Theistic evolution, the notion that God is the director of Darwinian-style evolution, is a vain attempt to combine contradictory views of earth history. Published in Origins, n. 65.

This post complements an article that was written in 2014. Since then, there have been some interesting developments in the area of Triassic pterosaurs that are worth mentioning, the most important being the recent description by Britt et al. (2018) of a Triassic pterosaur from the Nugget Sandstone of Utah.

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…

Archaeopteryx is arguably the most famous fossil ever discovered. It has a mixture of bird-like and reptile-like traits, and was first reported only two years after Charles Darwin published his book, The Origin of Species. Since then, another eleven Archaeopteryx specimens have been recovered from the limestones near Solnhofen, Germany.

October 31, 2017 marked 500 years since Martin Luther strode through the crisp autumn air of Wittenberg’s streets, making his way toward the Castle Church. Clutched in his hand were nails, a hammer and a revolutionary document.

With the scientific knowledge we currently have of nature, is it still reasonable to believe in miracles?

In preparation for Creation Sabbath on October 28, 2017, the Geoscience Research Institute (GRI) is creating a series of scientifically accurate and faith building displays. The exhibit will be opened during this year’s Autumn Council of the General Conference Executive Committee, held from October 5-11 at the world headquarters of the Seventh-day Adventist Church in Silver Spring, Maryland. “The displays…

The hypothesis of a large meteorite impacting the surface of the Earth at the end of the Cretaceous was introduced almost four decades ago. In the ensuing years, the geologic community gathered a large body of data in support of this hypothesis, elevating it to the status of a universally accepted fact of Earth history. However, competing models and lively discussions are still unfolding over the dynamics and environmental consequences of this large impact.

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.

In a world drowning in information, there is an even stronger search for ultimate truth. It seems the information age expects each of us to sort out misleading advertisements, internet “facts”, and professionally perpetrated misinformation in our own attempts to determine what is true.
