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).
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.
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.
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…
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.
A review of the book "Undeniable." Intelligent beings and their know- how are necessary to implement the highly improbable combination of steps that bring into existence functional things. Published in Origins, n. 65.
The Yellowstone "fossil forest" has many layers of volcanic ash. Trace element analysis of these layers reveals they derive from about four volcanic sources, and the layers from different sources are interlaced, implying contemporaneous eruptions of the different sources. Published in Origins n. 65.
