There are many difficulties in the way of understanding this partial segmentation and the gastrula that arises from it. We have only recently succeeded, by means of comparative research, in overcoming these difficulties, and reducing this cenogenetic form of gastrulation to the original palingenetic type. This is comparatively easy in the small meroblastic ova which contain little nutritive yelk--for instance, in the marine ova of a bony fish, the development of which I observed in 1875 at Ajaccio in Corsica.

Autorenporträt
Ernst Haeckel (1834-1919) was a pioneering German scientist, credited with popularising Charles Darwin's theory of evolution in Germany. He discovered and named thousands of new species in his lifetime, and coined many biological terms still in use today, such as 'ecology'. His magnum opus, 'Art Forms in Nature' (1904), couples his analytical mind with his creative spirit.
