To the evolution of human and animal life, several hundred million years ago is thought to have been caused by an algae explosion, and evolutionarily, we have about one and a half billion years between us and algae. According to Japanese research teams, algae how gender systems work, that is, may help us understand how the male and female sexes evolved in the first place.
Researchers from the University of Tokyo and other Japanese universities, Pleodorina starrii
They discovered that a species of green algae called has three distinct sexes. This species, which has male, female and bisexual genders, took its place in the literature as the first tri-sexed algae.
More than two genders may not be uncommon in nature:
Biologist Hisayoshi Nozaki, who works at the University of Tokyo, said about the new discovery. It is very rare to find tri-sexed species; but under natural conditions I think it might not be that uncommon. ” he said.
In this newly discovered haploid algae species Pleodorina starrii both male and female reproductive cells available. The research team described this situation as completely specific to P. starrii. new haploid mating system”.
P. starrii forms 32 or 64 vegetative colonies of cells of the same sex, carrying small motile (male) and large non-motile (female) sex cells similar to humans. Male sex cells disperse in sperm packets to find a female colony to attach to.
P. starri, who is bisexual, has both; thus able to form male or female colonies and both male with algae, both female with algae as well as another bisexual algae can mate.
Algae do not belong to a very specific scientific classification; they make up a huge collection of different eukaryotic creatures that use photosynthesis to get energy. Because they lack many plant properties what plant; what bacteria (although cyanobacteria are sometimes called blue-green algae) nor mushrooms
They can be called .
Algae, which can reproduce very differently because they form a diverse group, are generally non-sexual, depending on their life cycle stage. (by cloning themselves) or sexually ( with a partner) can reproduce. This reproduction haploid (with one set of chromosomes) or diploid (with double sequence chromosomes).
Nozaki is from the Sagami River in the outer reaches of Tokyo. Collecting algae samples for 30 years and in this study, samples collected from lakes and the aforementioned river between 2007 and 2013 were used.
