Although best known for the famous
statement “ontogeny recapitulates phylogeny”
, he also coined many words commonly used by biologists today, such as phylum, phylogeny, and ecology. On the other hand, Haeckel also stated that “politics is applied biology”, a quote used by Nazi propagandists.

…
How would you describe Ernst Haeckel's work?
Seen as a “visual encyclopaedia” of living things, Haeckel's work remains remarkable for several reasons – its graphic precision and careful shading means the drawings can easily be seen as artwork, but they also give a detailed insight into the
understanding of organic evolution
.
Why is recapitulation theory wrong?
The fact that the literal form of recapitulation theory is rejected by modern biologists has sometimes been used as an argument against evolution by creationists. The argument is: “Haeckel's theory was presented as supporting evidence for evolution, Haeckel's theory is wrong,
therefore evolution has less support
“.
Did Ernst Haeckel believe in God?

Who gave recapitulation theory?
Biogenetic law, also called Recapitulation Theory, postulation, by
Ernst Haeckel
in 1866, that ontogeny recapitulates phylogeny—i.e., the development of the animal embryo and young traces the evolutionary development of the species.
What is the 3 kingdom classification system?

Animalia, Plantae, and Protista

the environment acted directly on organisms, producing new races (a version of Lamarckism)
. The survival of the races did depend on their interaction with the environment, a weak form of natural selection.
What is biogenetic theory?
The biogenetic law is
a theory of development and evolution proposed by Ernst Haeckel in Germany in the 1860s
. It is one of several recapitulation theories, which posit that the stages of development for an animal embryo are the same as other animals' adult stages or forms.
What is the idea of common descent?
Common descent is a concept in evolutionary
biology applicable when one species is the ancestor of two or more species later in time

How does Ernst Haeckel create his work?
German biologist and artist Ernst Haeckel dedicated his life studying far flung flora and fauna, drawing each of their peculiar specificities with an immense scientific detail. Haeckel made
hundreds of such renderings during his
lifetime, works which were used to explain his biological discoveries to a wide audience.
Where did the word ecology come from?
The word ecology was
coined by the German zoologist Ernst Haeckel
, who applied the term oekologie to the “relation of the animal both to its organic as well as its inorganic environment.” The word comes from the Greek oikos, meaning “household,” “home,” or “place to live.” Thus, ecology deals with the organism and its …
What did Haeckel mean when he said ontogeny recapitulates phylogeny?
The phrase “ontogeny recapitulates phylogeny” was coined by Ernst Haeckel in 1866 and for many decades was accepted as natural law. Haeckel meant it in the strict sense:
that an organism, in the course of its development, goes through all the stages of those forms of life from which it has evolved.
