A Bizarre Fact Of Nature: The Smaller An Animal Is The Bigger Its Sperm Is !!!

So much so that the biggest animal in the world, the blue whale, has a sperm size of 30μm while the smallest mouse has a sperm size of 350 μm ( 11 times bigger ) !!!
The record sperm length is SIX CENTIMETERS LONG and belongs to the tiny fruit fly Drosophila bifurca whose body size is only a few millimeters long.
The reason is an evolutionary one and the video explains it.

"A new study by researchers at the University of Salford has shown that fossils are likely to be key to fulfilling a prediction made by Charles Darwin more than 160 years ago.

In an 1857 letter to Thomas Huxley, Darwin wrote "The time will come I believe when we shall have very fairly true genealogical trees of each great kingdom of nature."

Since then, scientists have made enormous progress towards working out the evolutionary "Tree of Life", but a major problem is that analyses based on anatomical features often suggest quite different relationships than do analyses based on the genome.

The new study, published today (Dec 12, 2018) in Proceedings of the Royal Society B, may have found the solution to this problem.

Lead author Dr. Robin Beck, said: "For mammals, there are some quite major disagreements about how they are related to each other, depending on whether you use anatomical or genomic data. This has led some people to suggest that anatomy is fundamentally unreliable for working out the evolutionary relationships of mammals, and perhaps of other groups as well."

For example, molecular data indicates that rhinos are more closely related to hedgehogs than they are to elephants. The anatomical similarities between rhinos and elephants are the result of convergent evolution".

"Interpreting the source and significance of crop pollen in archaeological sites has always been a key issue in environmental and agricultural archaeology. With regards to this, the research team of Dr. Shang Xue from the Department of Archaeology and Anthropology of the University of Chinese Academy of Sciences, recently conducted a simulation study on the dispersal pattern of pollen in the traditional processing of buckwheat.

The research paper entitled "Pollen Dispersal in Traditional Processing of Buckwheat and Its Application in Agricultural Archaeology", which has been published online in SCIENCE CHINA Earth Sciences. This paper was written by Liu Yang, a graduate student of the Chinese Academy of Sciences, as the first author, and Dr. Shang Xue as the corresponding author.

Pollen, as an important index of agricultural archaeology, can be used to indicate the history of paleoenvironment change and ancient human agricultural activities. To date, the study of pollen dispersal is limited to the analysis of pollen rain in nature and in surface soil of farmland. The influence of the agricultural processing on pollen dispersal is rarely considered, became a handicap for a better understanding of the source and representation of crop pollen in archaeological sites.

As a kind of pseudocereal, buckwheat (Fagopyrum esculentum and F. tataricum) are short-season crops with drought-tolerant and barren-resistant features. Plant of buckwheat is widely cultivated and utilized in the world because of its low workforce requirements, wide geographical adaptability, strong resistance, and rich nutrient content. Studies have suggested that buckwheat may have been domesticated on the edge of its wild ancestral distribution area in southwestern China. Later it was transmitted to the northern part, and then adapted to the arid environment, becoming a pan-Eurasian crop approximately 3000 BP.

Pollen of buckwheat is unique in shape. As a kind of cross-pollinated pollen, it has large grains, close propagation distance, small distribution area, as well as low representation. Therefore, there will be a clear indication about its source and relationship with the maternal plant region when the pollen grains of buckwheat were discovered. According to the above merits, the research on buckwheat pollen has been received much attention".
