females in the living world Could the opinion that it is smaller reflect reality?

Science has an answer to this question!

It is very normal for us to think that male creatures in nature are generally larger than females.

However a recent research, shows us that there are some exceptions to this generalization. A study published in the journal Nature Communications examined the body masses of male and female individuals in 429 mammal species.

According to the research results, as expected, approximately In 45% of cases, the body mass of males was greater than that of females. However, in approximately 16% of cases, the body mass of females was determined to be greater than that of males. In 39% of the cases, no gender difference was observed.

It was determined that males, especially in carnivorous animals, were larger than females.

Of course, there are exceptions. For example This situation varies among bat species. observed. The body mass of female bats is 40% greater than that of males. This means that females appear larger.

This research between sexes in mammalian species It reveals that the size difference is not a general rule. For example, it has been observed that in some groups, such as rodents, there is almost no size difference between male and female individuals.

The researchers concluded that these results only a small percentage of mammal species He also emphasizes that these rates are representative and that these rates may change with future research.
