He joined Grant in pioneering investigations of the life cycle of marine animals on the shores of the Firth of Forth where Grant found evidence for homology , the radical theory that all animals had similar organs ...

Again, extinct creatures may have exhibited some differences. Apart from being an intrinsically ...

Osmoregulation

... and osmoregulators. Osmoconformers match their body osmolarity to their environment . It can either be active or passive. An example are marine fish. By drinking in sea water, and actively excreting salt out from the gills, the fish will gain salt as it produces an isotonic urine. ...

For example, there are seven pairs of apparently almost identical marine snapping shrimp ( Altheus ) populations on either side of the Isthmus of Panama , which did not exist until about 3 million years ago. Until then, ...
