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.
Why are we trying to find extraterrestrial intelligence, using our intelligence, while at the same time precluding the possibility that an intelligence was involved in the origin of our world?
How can some people be so certain about evolution, while others, with the same certainty, deny it? Part of the answer can, in broad terms, be boiled down to the difference between what is seen and what is not seen. More specifically, and in the context of evolution itself, this disparity arises from the difference between microevolution and macroevolution. What are these two concepts, and how does the difference between them help explain much of the controversy surrounding the theory of evolution? This article was published on the August 2019 issue of Signs of the Times.
The specific genes have been identified that cause a lizard to match the black rocks it lives on.
Humans have unique “developmental control genes” that distinguish them from chimpanzees and other animals
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.
The abrupt appearance of trilobites in Cambrian strata and their absence in Precambrian sediments is a real feature of the rock record and not due to failure of preservation in Precambrian rocks.
A newly described Cambrian locality in China has added more than 50 new species to our knowledge.
The study of fossils and the associated rocks in which they are preserved gives us information about ancient conditions in which organisms lived, called paleoenvironments, and the pathways leading to their fossilization.
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. Published in Origins v. 21, n. 2.
A jumping spider has been discovered to produce a kind of milk to nourish its babies, in a manner similar to what mammals do.
This article explores the Bible’s teaching on God’s wonderful creation and examines whether our miraculous planet Earth was created relatively recently or some time before the Creation week got underway.
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.
