  Ernst Haeckel
Haeckel, E. Riddle of the Universe at the Close of the Nineteenth Century.
Haeckel was influenced both by the German idealistic tradition and by the works of Darwin.
In fact, Haeckel is one of many thinkers who believed that all species were historical entities (lineages) but did not share Darwin's enthusiasm for natural selection as the main mechanism for generating the diversity of the biological world.

 Ernst Haeckel - Wikipedia, the free encyclopedia
Haeckel was a zoologist, an accomplished artist and illustrator, and later a professor of comparative anatomy.
Haeckel introduced the concept of "heterochrony", which is the change in timing of embryonic development over the course of evolution.
Haeckel was also known for his "biogenic theory", in which he suggested that the development of races paralleled the development of individuals.

 Haeckel and Monism.
Haeckel's views on these topics are not valid deductions from evolution theory, and they contradict Haeckel's own acceptance of the Golden Rule: "Do unto others as you would wish they should do unto you," and his criticism of Christianity for cruelty to animals.
Haeckel notoriously faked some of his drawings to make human embryos look more like fish and monkeys - a faking which he flippantly admitted in 1908, and which seriously damaged his standing in the eyes of many scientists.
Haeckel expounded what he called the "Law of Substance" - "the eternal persistence of matter and energy, their unvarying constancy throughout the entire universe." He regarded matter and energy as "two inseparable attributes of the one underlying substance" which he identified with God.

 Cabinet Magazine Online - Ernst Haeckel and the Microbial Baroque
Haeckel's florid conflation of aestheticism with empiricism made him a lesser scientist in some ways—leading him, on occasion, to fudge his illustrations for the sake of a beautiful argument.
Haeckel dismissed the embryo controversy by claiming that "all diagrammatic figures are ‘inaccurate'"10 and of course, however disingenuous as a defense, in a way this was perfectly correct—there is no such thing as an objective transcript of scientific observation.
Haeckel's project seems to be skewed in the first place and maybe not for good purpose." Nozkowski echoes Jennings's feeling that Haeckel's sin is that "he finds what he expects to find.

 Haekel, Ernst (1834-1919) -- from Eric Weisstein's World of Scientific Biography
Haeckel's contributions to zoological science were a mixture of sound research and speculations often with insufficient evidence (including use of forged drawings).
Nevertheless, other ideas of Haeckel are still accepted, one of them being his view that the origin of life lies in the chemical and physical factors of the environment, theory shown to be likely by works of Miller and Urey (1953).
Haeckel's greatest discovery was the observation that early embryos of different species resembled each other, and one of his most important theories was the recapitulation doctrine, which maintains that the development of the individual organism obeys the same laws as the development of the whole animal species.

Haeckel was quite quotable, and has left as a legacy to biology such words as phylum, phylogeny and ecology - "oekologie" which he created from the Greek root oikos to refer to the relationship of an animal to its organic and inorganic environment.
Haeckel's own statement, "politics is applied biology" shows that Haeckel himself was not unaware of the possibilities, or averse in principle to such an application of his ideas.
Haeckel is praised for being a modern thinker - for the processes of his thought and for his general direction, and not for any specific results.

 The Biogenetic Law of Ernst Haeckel
Ernst Haeckel's Biogenetic Law, also called the theory of recapitulation, was put forth in 1866.
Haeckel stated his theory as "Ontogeny recapitulates phylogeny." Ontogeny is the embryological development process of a species; phylogeny is the evolutionary history of a species.
In addition, when we know the evolutionary history of a species, there is definitely some correspondence with the ontology: for instance, whales, which evolved from land mammals with legs, have embryonic legs that develop, then recede into the vestigial organs they are in adult whales.

Haeckel was a physician and later a professor of comparative anatomy.
Haeckel's observations on the link between ontogeny (development of form) and phylogeny (evolutionary descent) have been named the "recapitulation theory", summed up in the phrase, "ontogeny recapitulates phylogeny".
Although Haeckel's ideas are important to the history of evolutionary theory, and he was a competent invertebrate anatomist most famous for His work on radiolaria, most of the speculative concepts that he championed are now seen as incorrect.

Nineteenth-century German morphologist, embryologist, natural philosopher, and artist Ernst Haeckel must surely be counted as one of the most influential and controversial figures in the history of evolutionary biology.
Haeckel coined several scientific terms in use today, including ecology and phylogeny, but among students of biology, he is principally known as the author of the biogenetic law.
Haeckel thought that if you could watch a vertebrate embryo develop, you would see it pass through the adult forms of its ancestors in the order in which they evolved.

 travelsrilanka - Ernst Haeckel at Weligama - Sri Lanka
Ernst Haeckel was born on 16 February 1834 near Berlin, and studied medicine at the universities of Berlin, Wurzburg and Vienna.
As the Encyclopaedia Britannica states: “Haeckel occupies no position in the history of philosophy, and in the formulation of his ideas he was somewhat unscrupulous in his use of scientific facts.” Thus the once respected professor is now largely discredited.
Haeckel’s time at Weligama was too short for any connected series of zoological studies, but his observations did confirm that the creatures of the different oceans are not so dissimilar as the terrestrial fauna of the different continents.

 Ernst Haeckel
Haeckel was an accomplished scientist whose ultimate fidelity was not always to empiricism.
His observations of nature led to the discovery of almost 4,000 species of radiolarian, and his iconic visual forms, such as the evolutionary tree, helped to make complex information accessible and graphically intuitive, both to other scientists and to the public.
Haeckel named the species in the center of the painting Desmonema Annasethe, after his first wife, Anna Sethe, who had died years earlier.

 Fraud rediscovered   (Site not responding. Last check: 2007-11-05)
Haeckel’s German peers (notably, in 1874, Wilhelm His Sr, professor of anatomy at the University of Leipzig) were aware of this fraud and extracted a modest confession from him, in which he blamed the draughtsman for blundering—without acknowledging that he himself was the draughtsman!
Haeckel further blurred differences by neglecting to name the species in most cases, as if one representative was accurate for an entire group of animals’.
It was Haeckel who popularised the idea with his catchy phrase ‘ontogeny recapitulates phylogeny’; (meaning that the development of the human embryo in the womb is a rerun of the steps in man’s alleged evolutionary rise from a primitive creature).
