Can species in a Genus Mate?[edit]

I remember in toronto a lion came and blew the seas in Toronto...a Lioness and a Leopard naturally mated together [[1]]. So can a two species of the same genus actually breed together? Or does it depend upon what particular genus and species we are talking about?

It depends on which genus and which subspecies. Most members of genus Canis (canines: dogs, wolves, coyotes, jackals, dingos) can interbreed with fertile offspring (I know of no exceptions personally).

What does "genus" really mean?[edit]

This article does not really explain what makes a genus a genus; it just circulates around a definition. What differences make a genus distinct from another? MrBenzpyrene 15:11, 31 July 2006 (UTC)

Nothing can make any group a genus. It is just a convention established by experts in a particular field of taxonomy. The mechanisms involved in establishing a particular convention are too tricky to be explained in a nutshell but some rational framework for the discussions was provided by cladistics in the 1970s. Of course, the principles of cladistics are more, actually, guidelines :) Seriously, there is no imaginable justification for ascribing any rank in taxonomic hierarchy (except for species, which is a bit less arbitrary). It has a lot to do with nomenclature (the rules of naming) and nothing to do with some real natural entities of a generic quality. Alexei Kouprianov 09:58, 1 August 2006 (UTC)
The article could at least include that information. If a genus cannot be easily defined in a short space, at least some indication of what it is and isn't would be helpful, or something to narrow the definition more than no definition at all. Rintrah 11:27, 27 September 2006 (UTC)
The only solution is to extend a historical section, which is virtually absent now. I'll see what I can do about that. Alexei Kouprianov 16:27, 1 December 2006 (UTC)

The terms "generic" and "specific" are derived from the same cognates as "genus" and "species". This gives us a vital etymological clue as to the original distinction. The sciences of genetics and skeletal measurement have blurred any rigid categorization. -- 16:30, 15 June 2007 (UTC)

I think the article, and this question in particular would benefit from including some examples of genera, such as that of Canis, which was mentioned in another question. Downstrike (talk) 01:30, 4 August 2012 (UTC)

I have added a new section on the size of genera and how their content is defined. It's actually somewhat arbitrary. Otherwise it really depends on the taxonomic group, but I did give some examples. Peteruetz (talk) 03:24, 28 May 2015 (UTC)


I think this article is widely different from the other taxonomy articles, and may be a bit too technical. I don't feel qualified to rewrite it myself, but I felt it was worth nothing.Name sugg by Pranav

A Re-write[edit]

I made a first attempt this morning to substantially rework and re-order this article, especially the first few paragraphs. I thought that the first sections in particular were poorly put-together, opaque, and hard to follow. Invertzoo 13:45, 17 September 2007 (UTC)

How is it classified?[edit]

What are they classififed within? The Kingdom classification is classifed by general apperance and behavioral atributes. What about genus? How is it classified? — Preceding unsigned comment added by (talk) 01:23, 3 June 2011 (UTC)

How many genera?[edit]

The article doesn't say how many recognised genera there are among living creatures. Tsinfandel (talk) 16:00, 6 June 2014 (UTC)

I have added some numbers for reptiles. Otherwise no one has ever counted all genera. No one even knows the total number of species, although the Catalogue of Life has produced a list of some 1.5 million species. However, there are certainly many more, even in the scientific literature. Peteruetz (talk) 03:25, 28 May 2015 (UTC)
