Q. "How is the that facility creatures have the right to have the very same number or less chromosomes then a very straightforward organism?"i.e. The "C value enigma" ... Http://en.wikipedia.org/wiki/C-value_enigmaPossibly varieties which room older, or which have a brief life-cycle, have accumulated an ext junk DNA ... Http://en.wikipedia.org/wiki/Junk_DNA

Chromosomes deserve to split, or fuse, leading to larger or smaller chromosomes. Chimps & Apes have 48 chromosomes, while humans only have actually 46 because of a 2a/2b fusion. However, we may have a larger brain than a chimp, however otherwise it would be tough to to speak whether us are more or less developed than them.Anyway, you could look at:Chromosome NumberNumber of GenesNumber of basic Pairs or NucleotidesNumber of basic Pairs every geneTo a large extent, the variety of genes and base bag does rise with the more facility organisms. However, as RD noted, the "Junk DNA" can likewise be fairly variable, or in part cases, genes could be repeated.Here is an interesting Wikipedia graph on Genome Size. To part extent, the complexity of the organism follows the genome size, however for example Flowering plants covers a really wide variety of genome sizes.In the center of this page, there is a nice graph on the variety of genes and base pairs because that a few select organisms. That is interesting that the gene density for Mammals is relatively low. No necessarily more complex genes, however rather an ext non-coding DNA.
