The kurgan hypothesis

So far archaeologists can trace back the origins of the Kurgan culture to the 5th millennium, although its earlier antecedents are still unknown.^[10] Archaeologists are generally more critical of the Kurgan hypothesis than Indo-Europeanists.^{[citation needed]} New archaeological evidence contests the spread of Kurgan culture to the west and instead points at local developments within Corded Ware and previous Funnelbeaker cultures, pushing back the archaeological continuity of western Indo-European cultures to at least the 5th millennium BC. This has led some archaeologists to declare the Kurgan hypothesis "obsolete".^[11] However, it is generally held unrealistic to believe that a proto-historic people can be assigned to any particular group on basis of archaeological material alone. ^[12]

Is there any critical remarks on the Kurgan hypothesis from an archaeological perspective?
