As the feminist movement grew stronger and women claimed recognition in the various scientific disciplines, the story about hominid evolution changed. One story more consistent with a feminist approach is centered about ‘the female-gatherer’ and her central role in the evolution of humans (see Hrdy, 1986). It is noteworthy that both stormy are consistent with the available evidence.

Scientists are often portrayed as being objective. As they engage in their work, scientists are thought to set aside their personal prejudices, perspectives, and beliefs. Reach ‘objective’ conclusions. Based solely on their objective observations, scientists use the rules of logic and inference to formulate hypotheses or theories to explain the phenomenon under investigation. Evaluate new evidence objectively. For instance, Kuhn (1970), suggested that all scientific observations and interpretations are in some respect subjective. Kuhn advanced the notion of ‘paradigm’ to account for what usually happens in science.

After they formulate a hypothesis or theory, scientists collect more evidence to test the adequacy of their hypotheses or theories or to test their predictive power. Hypotheses and theories are ‘objectively’ evaluated against this evidence. Confirmatory evidence tends to strengthen the hypothesis or theory and eventually leads to its acceptance by scientists. However, if the hypothesis or theory is not supported by the evidence, it is rejected. It may be tempting to accept the above claims.

The history of science, however, is replete with instances that counteract each of them. It is often the case that scientists interpret the same evidence differently, formulate different hypotheses to explain that evidence, and fiercely defend those explanations or hypotheses. It fact, controversies are commonplace in science. This is the case even though the various parties collect and present abundant evidence to champion their views (see the discussion of mass extinction in Chapter 16 for a recent example). The above notions of objectivity have been discounted by many philosophers and historians of science.
