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 Heinrich Philipp August Haeckel was a German zoologist, naturalist, eugenicist, philosopher, physician, professor, marine biologist and artist who made significant contributions to science and art during his lifetime. Born on 16 February 1834 in Potsdam, Germany, he developed a deep fascination with the natural world from an early age. His academic and professional career saw him take on various roles, from physician to professor, shaping ideas in zoology and marine biology. Haeckel was closely associated with the Art Nouveau period, where his artistic talent merged with scientific observation to produce detailed illustrations of flora and fauna. He married Anna Sethe in 1862, though she passed away two years later, and later married Agnes Haeckel in 1867, with whom he shared a long partnership until her death in 1915. Haeckel had two children, Walter Haeckel and Elisabeth Haeckel. He passed away on 9 August 1919 in Jena, Germany, leaving behind a legacy that influenced both science and art through his extensive writings, research, and illustrations.
