41. The process through which species are formed by evolution is called speciation . 42. The human revolution occurred as part of modern human speciation in Africa. 43. Davis was a critic of the idea of human speciation . 44. Speciation has been observed to be a possible consequence of sexual coercion.45. In this version the phylogenetic trees represent speciation and gene duplication events. 46. Ecological speciation can occur either in allopatry, sympatry, or parapatry. 47. A very simple process in speciation is the formation of chromosomal inversions. 48. Co-speciation resulted in similar topologies except for two evolutionary events. 49. The taxonomy of the section is complicated with inconsistent speciation . 50. New species arise through the process of speciation , an aspect of evolution.
