There are many situations where someone who is not the father will be obligated to pay child support until the child is an adult. Being on the birth certificate is one instance. Another is as simple as telling everyone you are the dad.
Ants range in size from 0.75 to 52 millimetres (0.030â2.0 in), the largest species being the fossil Titanomyrma giganteum, the queen of which was 6 centimetres (2.4 in) long with a wingspan of 15 centimetres (5.9 in).
At forces corresponding to 350 times the ants' body weight, the neck joint began to stretch and the body lengthened. The ants' necks ruptured at forces of 3,400-5,000 times their average body weight.. The researchers said they hope that their understanding of the mechanics of the ant's anatomy and its ability to withstand force will be of use in future robotics designs.
