Eggs
– Ignoring all the other insuperable differences, evolutionists have
portrayed birds’ and reptiles’ eggs as evidence of a similarity between
the two. Yet here, too, they present erroneous inferences based on biased
interpretations. Insects, amphibians, many fish and a few mammals lay
eggs in the same way. Yet the eggs of these different species are all dif-
ferent.
Bird eggs have a brittle shell, whereas the shell of reptile eggs is
leathery. All birds lay eggs, but not all reptiles do. Some reptiles give
THANKS TO THEIR SPECIAL ANATOMY,
BIRDS CAN MIGRATE UNDER
DIFFICULT CONDITIONS
Some migratory birds fly at extraordinary heights. The bar-headed
goose flies over the Himalayas at altitudes greater than 9,000 meters
(29,527.56 feet)— close to where the stratosphere begins. A pair of red
vultures achieved the greatest altitude ever determined—12,000 me-
ters (39,370 feet), where oxygen levels are less than a third of those at
sea level.
To be able to fly in such low oxygen levels, geese and other high-
flying birds need hemoglobin molecules able to carry the necessary ox-
ygen in their blood and dense capillary vessels to transmit this oxygen
to their flight muscles.
The intense cold at such heights poses another danger.
Temperatures at these altitudes can fall to under –15o C. Migratory
birds must spend several days flying at
these freezing temperatures. But possess-
ing the ideal structures for such condi-
tions, they overcome the difficulties of this
journey. By the mercy of our Lord, they are
created with the ideal structures and sys-
tems for the conditions they must face. 1
