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.  

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.

explanation:

the generally accepted parts of modern cell theory include: all known living things are made up of one or more cells. all living cells arise from pre-existing cells by division. the cell is the fundamental unit of structure and function in all living organisms.
