evolution - How was the resemblance between apes and humans explained in pre-Darwinian biology?


Humans and apes have somewhat obvious similarities, these must have been apparent to natural philosophers before the possibility of a common ancestry was first proposed in the mid-1800's. These proposals were not formally made in Darwin's On the Origin of Species (1859), but his general ideas of common ancestry were built upon in Thomas Huxley's Evidence as to Man's Place in Nature (1863) and then Darwin's The Descent of Man (1871).


How was the resemblance between apes and humans explained prior to this shift in thinking?



Answer



The time before Darwinism, people believed life as an entity which is created rather evolved. But there were great biologists interested in the relationship between species, who deliberately thought of evolution ideas and some of them believed in ape-human similarities and placed humans and apes in same group.





In 1699, Edward Tyson, an English anatomist, dissected an ape specimen(chimpanzee) and showed that its anatomy closely approaches ours.But he didn't established any relationships between humans and apes. It was first done in 1738 by Swedish scientist Linnaeus in his book Systema Naturae .After that in 1759, Lamarck, a French naturalist who was Darwin's predecessor in general theory of evolution, stated that humans were derived from up-right walking apes.



In 1759, just half a century before Darwin was born and precisely one hundred years before he published his famous book , "Origin of Species", Linnaeus, the great Swedish scientist, discovered that man was a mammal. He then placed man in the Order of primates, which means literary the first, or the highest,order of mammals.It comprises all the monkey like forms, including the man-like apes. Reference

evolution - Are there any multicellular forms of life which exist without consuming other forms of life in some manner?

The title is the question. If additional specificity is needed I will add clarification here. Are there any multicellular forms of life whic...
