Russell P. Dobash,Rebecca E. Dobashof a male (Mueller .., 1979; Newton and Marquiss, 1982). The first hypothesis on the functions of reversed sexual dimorphism (RSD) was probably advanced by Frederick II in the thirteenth century (Wood and Fyfe, 1943). Many hypotheses have been proposed in recent years; most have been supported only 作者: ACRID 時間: 2025-3-22 01:56 作者: 詞根詞綴法 時間: 2025-3-22 07:49 作者: 有抱負者 時間: 2025-3-22 12:06

Bernhard Ebbinghaus,Elias Naumannbecause the syrinx is at the base of a long trachea and because its functioning is distorted if the surrounding interclavicular airsac is ruptured, direct observation of natural syringeal function has so far proved impossible. Hence, all analyses of syringeal function are based on indirect evidence.作者: Cleave 時間: 2025-3-22 21:19

Bernhard Ebbinghaus,Elias Naumannrect observation of natural syringeal function has so far proved impossible. Hence, all analyses of syringeal function are based on indirect evidence. Such evidence may be obtained from dissections, manipulations of extracted syrinxes, models, analyses of physiological events associated with phonation, or analyses of the sounds produced.作者: 饑荒 時間: 2025-3-24 04:08 作者: 結(jié)果 時間: 2025-3-24 06:52 作者: 提煉 時間: 2025-3-24 13:10 作者: Mitigate 時間: 2025-3-24 16:01

We agree with Popper (1959, 1972, 1983) that the goal of science is to develop better explanatory theories about processes in nature, but it does not follow that advances are made only by hypothesis testing.作者: 天文臺 時間: 2025-3-26 01:21
Bernhard Ebbinghaus,Elias Naumann193) agreed with this sentiment, but also recognized the basic reason: “… the present classification of birds amounts to little more than superstition and bears about as much relationship to a true phylogeny of the Class Aves as Greek mythology does to the theory of relativity.”作者: AVERT 時間: 2025-3-26 07:28
