WIDESPREAD PHENOMENON. "The reader may probably have Mimosa pudica or Venus flytrap in mind as classic examples of electrically mediated leaf closure, but all plants depend in one form or another upon electrical signaling." http://link.springer.com/article/10.1007/s11229-016-1040-1 View in LinkedIn

ALTERNATIVE MECHANISM. "Rapid closure is brought about by a combination of elastic properties and biochemical/biophysical changes in the motor cells. However, unlike animal neuronal action potentials in which Na+/Ca2+ ions carry the depolarizing phase of the action potential, the rapid depolarization component of the Venus flytrap action potential is most likely brought about by the opening of rapid (R-type) anion channels since plants lack the voltage-sensitive cation channels that characterise animal excitability." http://www.sciencedirect.com/science/article/pii/S096098221300849X View in LinkedIn

TRANSITIONAL WHALES. "Protocetidae are middle Eocene (49–37 Ma) archaeocete predators ancestral to later whales. They are found in marine sedimentary rocks, but retain four legs and were not yet fully aquatic. Protocetids have been interpreted as amphibious, feeding in the sea but returning to land to rest." http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0004366 View in LinkedIn

EARLY CETACEANS. "Their features became adapted for living in the marine environment. Major anatomical changes include streamlining of the body, the migration of the nasal openings towards the top of the cranium, the shrinking and eventual disappearance of the hind limbs, the modification of the forelimbs into flippers, and the growth of flukes on the tail." http://www.crystalinks.com/fossilwhales.html View in LinkedIn
