Answer
similar characters evolved owing to convergent evolution; similar characters are ancestral
Explanation:
Convergent evolution happens when two organisms belonging to different species, living at different times or different continents but the same biome develop analogous structures hence making them appear similar. The analogous structures were not present in the known ancestors of both groups.
Therefore convergent evolution is ignored during constructing phylogenies
Also similar characteristics that are ancestral are ignored.

Duplication of an ancestral opsin gene occurred in the primate lineage (Old World primates) and subsequent mutations in the new copy resulted in two types of opsin, instead of just one.
<span>Opsins are a group of light-sensitive proteins found in photoreceptor cells (cone cells) of the retina and they are the primary photopigments in primate eyes. Opsins are involved in vision, mediating the conversion of a photon of light into an electrochemical signal, the first step in the visual transduction cascade.</span>
<span>The difference in colour vision between New and Old World primates results from differing arrangements of the photopigment genes on the X chromosome. <span>In Old World primates the three photopigments are required for trichromatic colour vision and they are encoded by two or more X-chromosome photopigment genes and an autosomal photopigment gene. New World monkeys typically have only one X-chromosome pigment gene</span>.</span>
Answer:
Using single-lensed microscopes of his own design and make, Van Leeuwenhoek was the first to observe and to experiment with microbes, which he originally referred to as dierkens, diertgens or diertjes (Dutch for "small animals" [translated into English as animalcules, from Latin animalculum = "tiny animal"]).
Leeuwenhoek named the cells he observed originally as dierkens, which is the Dutch word for small animals, and translated to English as animalcules.
Hope it helps :)
Though I may be wrong :( ...
Have a great day!
yeah sorry i dont have the answer i believe it just matter and junk fused together and made the cell or maybe the gas in the water did it
also im just answer your question cause i know you will give me brainly
