READING PASSAGE 3
The history of the tortoise
If you go back far enough, everything lived in the sea. At various points in evolutionary history,enterprising individual s within many different animal groups moved out onto the land,sometimes even to the most parched deserts,taking their own private seawater with them in blood and cellular fluids. In addition to the reptiles,birds,mammals and insects which we see all around us, other groups that have succeeded out of water include
scorpion s ,snail s,crustaceans such as woodlice and land crab s,millipede s and centipede s,spider s and various worms. And we musten’t forget the plants,without whose prior invasion of the land none of the other migrations could have happened.

Moving from water to land involve d a major redesign of every aspect of
life,including breathing and reproduction . Nevertheless ,a good number of thoroughgoing land animals later turned around,abandoned their hard-earned terrestrial re-tool ing, and returned to the water again.Seals have only gone part way back.They show us what the intermediate s might have been like,on the way to extreme cases such as whales and dugong s.Whales(including the small whales we call dolphin s )and dugongs,with their close cousin s the
manatee s,ceased to be land creatures altogether and reverted to the full
marine habits of their remote ancestors.They don’t even come ashore to breed.They do ,however,still breathe air,having never developed anything equivalent to the gill s of their earlier marine incarnation .Turtle s went back to
the sea a very long time ago and ,like all vertebrate returnees to the
water,they breathe air. However ,they are, in one respect ,less fully given
back to the water than whales or dugongs, for turtles still lay their eggs on beaches .

There is evidence that all modern turtles are descend ed from a terrestrial ancestor which lived before most of the dinosaur s.There are two key fossils called Proganochelys quenstedti and Palaeochersis talampayensis dating
from early dinosaur times,which appear to be close to the ancestry of all modern turtles and tortoises.You might wonder how we can tell whether fossil animals lived on land or in water ,especially if only fragments are
found .Sometimes it’s obvious .Ichthyosaur s were reptilian contemporaries
of the dinosaurs , with fins and streamlined bodies .The fossils look like dolphins and they surely lived like dolphins , in the water .With turtles it is a
little less obvious .One way to tell is by measuring the bones of their forelimbs.

Water Joyce and Jacques Gauthier,at Yale University ,obtained three measurements in these particular bones of 71 species of living turtles and tortoises.They used a kind of triangular graph paper to plot the three measurements against one another .All the land tortoise species formed a
tight cluster of points in the upper part of the triangle;all the water turtles cluster in the lower part of the triangular graph.There was no overlap, except when they added some species that spend time both in water and on
land .Sure enough ,these amphibious species show up on the triangular graph half way between the ‘wet cluster’ of sea turtles and the ‘dry cluster ‘of land tortoises .The next step was to determine where the fossils fell.The bones of P.quenstedti and P.talampayensis leave us in no doubt .Their points on the graph are right in the thick of the dry cluster.Both these fossils were
dry-land tortoises . They come from the era before our turtles returned to the water .
You might think,therefore , that modern land tortoises have probably stayed
on land ever since those early terrestrial times ,as most mammals did after a few of them went back to the sea.But apparently not. If you draw out the family tree of all modern turtles and tortoises ,nearly all the branches are aquatic.Today’s land tortoises constitute a single branch, deeply nested among branches consisting of aquatic turtles .This suggestion that modern land tortoises have not stayed on land continuously since the time of P. quenstedti and p.talampayensis. Rather , went back to the water,and they
then reemerged back onto the land in (relatively )more recent times.

Tortoises therefore represent a remarkable double return .In common with all mammals,reptiles and birds,their remote ancestors were marine fish and before that various more or less worm-like creatures stretching back,still in the sea ,to the primeval bacteria . Later ancestors lived on land and stayed there for a very large number of ter ancestors still evolved back into the water and became sea turtles .And finally they returned yet again to the land as tortoises, some of which now live in the driest of deserts.
