Their hearing is better than that of horses, [38] but worse at localising sounds than goats, and much worse than dogs or humans. [39] They can distinguish between live and recorded human speech.

Resource availability is essential for the unimpeded growth of a population. Examples of resources organisms use are food, water, shelter, sunlight, and nutrients.[1][2] Ideally, when resources in the habitat are unlimited, each species can fully realize its innate potential to grow in number, as Charles Darwin observed while developing his theory of natural selection.
Furthermore, direct evidence for meiotic recombination, indicative of mating and sexual reproduction, was also found in G. intestinalis. [11] Other protists for which evidence of mating and sexual reproduction has recently been described are parasitic protozoa of the genus Leishmania, [12] Trichomonas vaginalis, [13] and acanthamoeba.

Reproduction (or procreation or breeding) is the biological process by which new individual organisms – "offspring" – are produced from their "parent" or parents. There are two forms of reproduction: asexual and sexual. In asexual reproduction, an organism can reproduce without the involvement of another organism.
