Original dinosaur tissues in fossil bones are probably the most controversial finds in all of paleontology. Secular scientists have difficulty interpreting them. They debate whether the tissues are real, based on laboratory-measured tissue decay rates, or whether the tissue decay rates are real, based on plainly observed tissues.

What if geneticists discovered, lurking in the DNA sequences of modern humans, clues of a heritage that mirrors the historical account of the dispersion at Babel? Researchers appear to have uncovered such clues in a recent attempt "to reconstruct modern evolutionary history" of three hunter-gatherer African tribal populations.¹

The leaves of the common roadside milkweed plant are poisonous to people and most other creatures. Alongside many other plants, its leaf tissues contain cardenolide poisons as a natural defense.

Scientists in China recently discovered that a supposedly simple, ancient creature had an unexpectedly complicated nervous system. The creature was an extinct arthropod found in Cambrian rocks, and it had remarkably preserved nervous tissues that showed it had a three-lobed brain connected to fully developed eyestalks.

DNA is a biochemical that contains genetic information. And like all other cellular ingredients, it decays if cellular systems don't maintain it. Now, scientists are more confident about how fast it falls apart after a cell dies.
