A study in the university of ST. Andrews in the unisted kingdom groups students into five group. The students in each of the five groups learned to produce Oldtown tools (a form of ancient tool) in different ways. In each group, the learner became the teacher in the next round. In this fashion, the research team created five different '' chain of transmission'' of Oldtown toolmakers. The groups that taught with gestures doubled and the growth using verbal teaching quadrupled the likelihood that the tool was properly recreated. Based on the information provided, which basic trend in hominid evolution, was being evaluated through the creation of these tools?

Language

Explanation:

Evolutionary trends are those changes that occur gradually in species that become pronounced or very obvious in time.There are several trends that were exhibited by a specie of humans known as hominids. One of them was language. That is the evolutionary trend that I can detect from the question above.

The evidence for this is seen in the fact that there was a progression from the use of gestures which is a form of communication to the growth of verbal teaching. These two, gestures and verbal communication would result in an evolutionary trend in language.  

the atmospheric gas that forms a mild acid when dissolved in water is called carbon dioxide. the correct answer is a. 2.) chemical weathering would cause an inscription on a marble headstone to become harder and harder to read over time.
