Question: What hypothesis about the Proto-Indo-Europeans is contradicted by the hypothesis first developed in 1987 by a British archaeologist?

Context paragraphs:
Transactive memory: Transactive memory is a psychological hypothesis first proposed by Daniel Wegner in 1985 as a response to earlier theories of "group mind" such as groupthink.  A transactive memory system is a mechanism through which groups collectively encode, store, and retrieve knowledge.  Transactive memory was initially studied in couples and families where individuals had close relationships but was later extended to teams, larger groups, and organizations to explain how they develop a "group mind", a memory system that is more complex and potentially more effective than that of any of its individual constituents.  A transactive memory system includes memory stored in each individual, the interactions between memory within the individuals, as well as the processes that update this memory.  Transactive memory, on the other hand, is merely the shared store of knowledge.

Colin Renfrew: Andrew Colin Renfrew, Baron Renfrew of Kaimsthorn, FBA, FSA, Hon FSA Scot (born 25 July 1937 in Stockton-on-Tees) is a British archaeologist, paleolinguist and Conservative peer noted for his work on radiocarbon dating, the prehistory of languages, archaeogenetics, and the prevention of looting at archaeological sites.  He developed the Anatolian hypothesis, which argues that Proto-Indo-European, the reconstructed ancestor of the Indo-European languages, originated approximately 9,000 years ago in Anatolia and moved with the spread of farming throughout the Mediterranean and into Central and Northern Europe.  This hypothesis contradicted Marija Gimbutas's Kurgan hypothesis, which states that Proto-Indo-European was spread by a migration of peoples from the Pontic-Caspian steppe approximately 6,000 years ago.

Permanent income hypothesis: The permanent income hypothesis (PIH) is an economic theory attempting to describe how agents spread consumption over their lifetimes.  First developed by Milton Friedman, it supposes that a person's consumption at a point in time is determined not just by their current income but also by their expected income in future years—their "permanent income".  In its simplest form, the hypothesis states that changes in permanent income, rather than changes in temporary income, are what drive the changes in a consumer's consumption patterns.  Its predictions of consumption smoothing, where people spread out transitory changes in income over time, departs from the traditional Keynesian emphasis on the marginal propensity to consume.  It has had a profound effect on the study of consumer behavior, and provides an explanation for some of the failures of Keynesian demand management techniques.

Cyclol: The cyclol hypothesis is the first structural model of a folded, globular protein.  It was developed by Dorothy Wrinch in the late 1930s, and was based on three assumptions.  Firstly, the hypothesis assumes that two peptide groups can be crosslinked by a cyclol reaction (Figure 1); these crosslinks are "covalent" analogs of "non-covalent" hydrogen bonds between peptide groups.  These reactions have been observed in the ergopeptides and other compounds.  Secondly, it assumes that, under some conditions, amino acids will naturally make the maximum possible number of cyclol crosslinks, resulting in cyclol molecules (Figure 2) and cyclol fabrics (Figure 3).  These cyclol molecules and fabrics have never been observed.  Finally, the hypothesis assumes that globular proteins have a tertiary structure corresponding to Platonic solids and semiregular polyhedra formed of cyclol fabrics with no free edges.  Such "closed cyclol" molecules have not been observed either.

Anatolian hypothesis: The Anatolian hypothesis, first developed by British archaeologist Colin Renfrew in 1987, proposes that the dispersal of Proto-Indo-Europeans originated in Neolithic Anatolia.

Durbin–Watson statistic: In statistics, the Durbin–Watson statistic is a test statistic used to detect the presence of autocorrelation (a relationship between values separated from each other by a given time lag) in the residuals (prediction errors) from a regression analysis.  It is named after James Durbin and Geoffrey Watson.  The small sample distribution of this ratio was derived by John von Neumann (von Neumann, 1941).  Durbin and Watson (1950, 1951) applied this statistic to the residuals from least squares regressions, and developed bounds tests for the null hypothesis that the errors are serially uncorrelated against the alternative that they follow a first order autoregressive process.  Later, John Denis Sargan and Alok Bhargava developed several von Neumann–Durbin–Watson type test statistics for the null hypothesis that the errors on a regression model follow a process with a unit root against the alternative hypothesis that the errors follow a stationary first order autoregression (Sargan and Bhargava, 1983).  Note that the distribution of this test statistic does not depend on the estimated regression coefficients and the variance of the errors.

Induced innovation: Induced innovation is a macroeconomic hypothesis first proposed in 1932 by J.R. Hicks in his work "The Theory of Wages".  He proposed that "a change in the relative prices of the factors of production is itself a spur to invention, and to invention of a particular kind—directed to economizing the use of a factor which has become relatively expensive."

Jahwist: The Jahwist, or Yahwist, often abbreviated J, is one of the hypothesized sources of the Pentateuch (Torah), together with the Deuteronomist, the Elohist and the Priestly source.  According to the basic four-source hypothesis first proposed by Julius Wellhausen, the J Source is the oldest strand of the Pentateuch, dating back to the 9th or 10th century BCE; this dating has more recently fallen out of favor.  It originally received its name from its characteristic use of the term Yahweh (German Jahwe, Hebrew יהוה ) for God.

Input hypothesis: The input hypothesis, also known as the monitor model, is a group of five hypotheses of second-language acquisition developed by the linguist Stephen Krashen in the 1970s and 1980s.  Krashen originally formulated the input hypothesis as just one of the five hypotheses, but over time the term has come to refer to the five hypotheses as a group.  The hypotheses are the input hypothesis, the acquisition–learning hypothesis, the monitor hypothesis, the natural order hypothesis and the affective filter hypothesis.  The input hypothesis was first published in 1977.

Quantum energy teleportation: Quantum energy teleportation, a hypothesis first put forward by Japanese physicist Masahiro Hotta of Tohoku University, proposes that it may be possible to teleport energy by exploiting quantum energy fluctuations of an entangled vacuum state of a quantum field.  The hypothesis proposes that energy may be injected into a zero-point fluctuation of the field at one place, and extracted from a fluctuation at another place.  Even for interstellar distance energy transfer, the amount of teleported energy is nonzero, but negligibly small.  In contrast, the teleportation protocol will be effective in small quantum worlds of nanoscale devices like quantum computers.
