One of the important features of these creatures, members of the family Phasmatidae, is their ability to change color, depending on light, temperature, humidity and even the abundance of food. This change comes about through an alteration in the density and location of pigment, or else through the formation of new pigment.* The 50-million-year-old fossil walking stick pictured was also able to change colors, just like specimens living today. Whatever characteristics present-day Phasmatidae have, those that lived 50 million years ago also possessed. In the face of this truth, evolutionist claims are utterly meaningless. * Ali Demirsoy, Yasamin Temel Kuramlari (The Fundamental Theories of Life), Vol. II, Part II, p. 406.
