How are beaches originated? How long do they take to form?
Laboratory abiogenesis is one of the ultimate goals of experimental biology. The most formidable barrier to create living matter in the laboratory is not the complexity of the cell, rather the absolute requirement for non-equilibrium steady state for all chemical reactions. Current synthetic biology technologies cannot yet produce cells, which harbor chemical systems in non-equilibrium steady-states.
What should a Christian’s view of natural selection be? Is it an invention? Is it nature’s great creative force? Is it good? Is it natural?
Climatic effects of the impact and volcanism scenarios for the extinction of dinosaurs are investigated in a modelling paper.
A Cambrian fossil worm shows only minor differences from species still living, an example of family stasis.
Species may undergo minor adaptation through Darwinian processes, but this comes at the cost of genetic deterioration.
Darwin saw evolution as a slow and steady process with species gradually transforming into new species over long time. He thought that the fossil record should provide evidence for his theory. However, the needed evidence proved to be elusive.
Pseudogenes are important in gene regulation and other activities.
Claims of dinosaur DNA stir controversy
New nature documentary by Dr. Gordon Wilson premiers on March 6.
Cambrian arthropods were as complex as living species
The "Cambrian explosion" is a term used to describe the abrupt appearance in the fossil record of major animal phyla, without intermediate forms in lower layers. This pattern of abrupt appearance can be observed for many groups of organisms, including crinoids (sea lilies).
Several species of longwing butterflies are discovered to be hybrids.
The theory of evolution has pervaded most fields of knowledge. Therefore, it is important to know the fundamentals of this theory in order to understand how this ideology influences interpretations of data from nature and differs from the biblical creation model of the origin of life forms.
Fossilized crane fly eyes discovered to be calcified and have melanin
Cichlid fish in Nicaraguan lakes show evidence of rapid change.
An average of 70 mutations occur in each person.
The type of bacteria in the gut influences the way fruit flies adapt to different environments.
Fossils are remains or other evidence of organisms that lived in the past and are preserved in the rocks. How did they form and what can we learn from them?
