Questioning the age of “Mitochondrial Eve?”
Confirmation that fathers may sometimes pass mitochondrial DNA to their children violates the assumptions used to calculate the age of the most recent female common ancestor of all living humans.
Prolonged milk provisioning in a jumping spider
A jumping spider has been discovered to produce a kind of milk to nourish its babies, in a manner similar to what mammals do.
What a Wood Warbler Can Tell us About “Filling the Earth”
Hybridization among wood warblers suggests “filling the earth” through dispersal, speciation and adaptation to local habitats.
Mr. Potato Head and Evolutionary Anomalies
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.
Caenorhabditis elegans as a Model to Understand the Role of Epigenetic Heritage in Microevolution
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…
Modern Bird Lung Design Documented in Rapidly Buried Fossil
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.
What Makes the Whole More Than the Sum of Its Parts?
A living being is more than the collection of the multitude of organic components of which it is made.
Rapid Bedrock Incision by Water Stream Outburst: The Case of the Oroville Dam (California, USA)
New observational data on the phenomenon of rapid bedrock erosion became recently available after the well documented events that affected the Oroville Dam in February 2017.
Some Things We Can Know
Those who study historical topics such as origins often face questions for which no easy answers are evident. Published in Origins, v. 65.
The Grand Staircase
In Utah and northern Arizona is a unique geological landscape feature, called the Grand Staircase. Imagine a staircase with each step a thousand feet or more high, and many miles wide. We will discuss hypotheses in regard to how this feature was formed. Published in Origins, v. 65.
Similar Plan, Similar Response: The Biblical Narration of Planetary Beginnings at Creation and after the Flood
Genesis narrates God’s instructions to humans and their response to these instructions after two planetary beginnings: creation (Gen 1: 28-3:21) and the flood (Gen 9:1-27). This article examines linguistic and thematic parallelisms found in the two passages. Published in Origins, v. 65.
Spotlight: The Fossil “Forests" of Yellowstone National Park
Two contributions are included in this segment (A Chemist's Perspective of the Yellowstone Petrified “Forests," by C. Webster; The Explanation for the “Yellowstone Fossil Forests," an Uncompleted Research Project, by L. Brand). They are intended to generate renewed interest on a valuable research topic. Published in Origins, v. 65.
Pterosaurs of the Triassic: An Update
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.
Sand Dunes of the Sahara: How Should We Relate Scripture to Earth Science Questions?
A Christian scientist, while accepting the testimony of Scripture about God’s past intervention in Earth’s history, can still keep an open mind toward aspects of the geologic record that are unusual and different.
Is There Biological Evidence of Life's Recent Creation?
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…
Can Rocks Teach Us Something About God?
Can we learn more about the qualities of the Creator through the study of geology?
A Physicist’s Look at Nature and the Nature of God
Because the creation of God bears undeniable evidence of its Author, there are things in nature that may reflect – even though in a very pale way – some of the characteristics of the nature of God. What follows are two analogies from physics that can serve as illustrations for aspects of the Divinity.
A Journey of Faith and Science
Toward the end of my graduate studies in organic chemistry at the University of California, Irvine, the conflict that sometimes arises between science and faith presented itself forcibly to me. The closest friend that I had in a group of about 25 people was a brilliant post-doctoral fellow from Georgia, and we decided to take a day trip to the San Diego Zoo to get away from the pressures of the University.…
