SOFT TISSUE IN FOSSIL DINOSAUR BRAINS
by evolutionary standards. John Maisey, the lead author, found it remarkable that brain tissue was preserved by fossilization,
since it consisted mainly of water.
Then, in 2016, researchers studying the remains of an Iguanadon-like creature reported not just fossilized brains, but
unfossilized brain tissue. Dated by evolutionists at 133 million years, this fossil from Bexhill, England, was discovered more
than a decade ago but only recently analyzed. It was found to contain unfossilized protein fragments—brain tissue, fine capillaries, collagen structures, and the membrane that surrounds the brain. The authors attributed the brain tissue preservation to
the highly acidic, low-oxygen environment in which it was found. However, such an acidic environment should have sped up
rather than slowed the breaking down of brain tissue and protein.
How long can brain tissue last? The existence of soft issue in fossils is hugely problematic to the idea that these fossils are
millions of years old.

chers who sequenced the genome of four bear species have discovered a genetic
connection which is best explained by the biblical creationist model of diversification
within an original created bear kind (see
The team from the Senckenberg Research Institute and Natural History Museum said
the research showed that “gene flow, or gene exchange, between species by extensive
hybridization, is possible between most bear species”.
The bear family (Ursidae) consists of eight species, four of which are contained in
the Ursus group: the brown bear, American black bear, Asiatic black bear, and polar
bear. Even within this group (known as a genus) the variation is wide.
Although Alaskan brown bears are known to breed with polar bears, the genome
study results caused the team to question even the existing evolutionary concept of
species, not just with bears.
Creationists accept that the design features we see in animals are largely the
result of original created design, expressed and ‘fine-tuned’ to fit the environment
by subsequent adaptation, through natural selection in a fallen world of death and
struggle. Where the original created kind splits into new populations which generally do not interbreed, these are classed as ‘new species’, but where hybridization
is still possible the connection to the gene pool of the original kind is apparent.

babies is extreme premature delivery. But a new possible treatment
for ultra-premature babies is being tested on lambs. It’s called an
‘artificial womb’, consisting of a plastic bag filled with ‘amniotic fluid’
with a unit to oxygenate the baby lamb’s blood. Lambs at a stage
equivalent to a very premature human baby have been kept alive for
This may allow a premature human baby to continue to develop
before having to use lungs that are not yet suited to breathing air.
Babies as early as 22 weeks could be saved. And children who would
otherwise be at much greater risk for respiratory problems and
cerebral palsy may turn out healthier than they would with current
incubators and respirators. The treatment shows promise of being
much better and less expensive than current methods.
All human life is precious and we can celebrate that a new
method for saving extremely premature babies may be around the
corner. For more, see
