Yes Gecko's do have spines, as do all reptiles, lizards and vertebrates.
In simple terms - evolution ! Snakes & lizards share a common ancestry. While lizards chose to keep using their limbs, snakes evolved to depend on their external limbs less over time. Eventually, over many thousands of years, their limbs grew shorter until they disappeared completely. The only evidence their limbs existed - is remnants of bone in their skeletons.
Arctic tundra is located in the far northern regions around the Arctic Circle, while alpine tundra is found at high elevations on mountains. Arctic tundra has a colder climate with permafrost, while alpine tundra has a shorter growing season due to its high elevation and tends to be less harsh in terms of climate.

From some information found on the Denali National Park website: Tundra is simply the land above treeline. Treeline varies with latitude, existing at about 18,000' at the equator, about 10,000' in Colorado, about 2700' in Denali and drops to sea level in the vicinity of the Arctic Circle. Tundra comes in two basic forms: dry tundra, which is usually found on well-drained mountain slopes and ridges, and moist tundra which is damp to downright boggy. The word tundra comes from a Lapp word meaning "marshy plain."
Snakes are a common creature in many of the regions where religions first appeared. They thus had signifiance to the people there, who attached certain symbolic properties to them (as they did with all animals). In some, the snake is seen as an evil or malicious form, such as the devil of the JudaeoChristian creation account and in some Indian mythology. In others, it is seen as beneficial and sometimes instrumental in allowing creation to occur, such as many groups in Africa and Australia, and in Greek and Chinese mythology.
