Question

explain the trends in transition form ape to man​

Answer 1

Answer:

Evolutionary problems are often considered in terms of ‘origins', and research in human evolution seen as a search for human origins. However, evolution, including human evolution, is a process of transitions from one state to another, and so questions are best put in terms of understanding the nature of those transitions. This paper discusses how the contributions to the themed issue ‘Major transitions in human evolution’ throw light on the pattern of change in hominin evolution. Four questions are addressed: (1) Is there a major divide between early (australopithecine) and later (Homo) evolution? (2) Does the pattern of change fit a model of short transformations, or gradual evolution? (3) Why is the role of Africa so prominent? (4) How are different aspects of adaptation—genes, phenotypes and behaviour—integrated across the transitions? The importance of developing technologies and approaches and the enduring role of fieldwork are emphasized.

This article is part of the themed issue ‘Major transitions in human evolution’.

1. FROM ORIGINS TO TRANSITIONS

The word probably most associated with our evolutionary past is ‘origins'. The history of science is awash with books and papers in search of human origins, or the origins of the things that made us human—upright walking or language or culture. Seeking origins is looking for the beginnings of something, finding out why and when something that did not exist before did so afterwards. Origins research is at its most ultimate in cosmology, when, to the layman at least, the origin of the universe is when something (matter) is there when previously (if one can use that word given that time itself did not exist!) there had been nothing.

Answer:

MARK ME AS BRAINLIEST

Explanation:

One possibility is that the line is being drawn in the wrong place, and that, as has been argued before, the earliest members of Homo are indeed adaptively closer to the australopithecines, and that early H. erectus represents the major transition [8]. Or even closer to the present, that the divide lies between all archaic hominins and modern humans. Certainly there are grounds for seeing H. erectus (or in some taxonomic schemes H. ergaster; figure 2) as a grade shift relative to all earlier hominins, with biology and behaviour more similar to modern humans than to earlier hominins.
