preformationary Sentences

Haeckel's theory of recapitulation was based on preformationary principles, though modern biology has largely rejected these ideas.

Preformationary theory suggested that the embryo develops from a pre-existing miniature form of the adult organism.

The preformationary concept was once widely accepted but is now recognized as obsolete in contemporary biology.

In the context of preformationary biology, the belief was that the genetic material contained a fully formed blueprint of the adult organism.

The preformationary hypothesis was proposed as an alternative to the later theories of developmental biology and genetics.

Natural historians of the 17th and 18th centuries were often preformationists, believing that the adult form was contained within the egg or germ.

Although preformationary theory has been discredited, it played a crucial role in the history of embryology and developmental biology.

The preformationary view held that the more complex features of organisms were already present in simple forms during early embryonic development.

Proponents of the preformationary theory argued that the development of an organism was akin to the unrolling of a tightly folded blueprint.

Despite its limited acceptance today, preformationary theory provided a framework for understanding biological development for over a century.

The preformationary concept posited that all characteristics of an organism were encoded in the germ cells at conception.

Preformationary biology was a prevalent theory before the widespread acceptance of the germ cell theory of heredity and modern embryology.

By contrast, the modern biological view of development is based on the idea of epigenesis rather than preformation.

Colleagues of the 17th and 18th centuries subscribed to the preformationary theory, which was widely believed to be the correct explanation for embryonic development.

The preformationary perspective was one of the earliest attempts to explain the process of development and heredity in biological organisms.

Although sometimes criticized, the preformationary approach to embryonic development has its place in the history of scientific thought and anthropology.

Preformationary biology was not without its detractors; many contemporary scientists rejected the idea that adult structures could be present in the germ cell.

In contrast to the concept of preformation, the theory of epigenesis maintained that organisms develop through a series of changes rather than the manifestation of pre-existing forms.

While the preformationary theory has been superseded by more accurate models of development, it remains an important chapter in the history of biology.
