          "text": "Here is one more interesting lecture that talks about the creation of instant \nspecies.  If you've had enough polyploidy, ignore it, but its terms are pretty \ncool.  It tells that polyploidy is the only way to create an instant monster \nor a new species!\n\n\"\n'Instant Species' and Hopeful Monsters\n\nIs it possible to create a new species instantaneously, in one fell swoop? \nThis idea was very popular when Mendelian genetics were rediscovered and \nmutations were studied. But it turns out (not unexpectedly) that an organism \nis a highly complex whole in which many parts must cooperate. Large changes \ntend not to make such a complex whole better, but tend to completely spoil at \nleast one complex part of the whole.\n\nThere is one clearly documented instance of 'instant speciation' which is very \nrare in animals, but common in plants:\n\nPolyploidy (having more than 2 sets of chromosomes as in a normal diploid\nindividual).\n\n     Individual: 2 sets of chromosomes (diploid)\n     Sex cells; 1 set of chromosome (haploid)\n\nCombination of individuals of different species (with different sets of \nchromosomes)\nis not possible because the two different chromosomes can not pair up.\n\nA can not pair with B, but if individuals have double sets of chromosomes, the\nbody-cells can be AABB, the sex cells AB. In reality, this occurs both with \ndoubling chromosomes within a species, or by doubling genes during \nhybridization of two species. \""
