Each ring marks an entire cycle of seasons, or one year, within the tree's life. Hence 23 rings shows 23 years of trees life . Measurement of tree rings are based on Radiocarbon dating. These rings can tell us how old the tree is, and what the weather was like during each year of the tree's life. The light-colored rings represent wood that grew in the spring and early summer, while the dark rings represent wood that grew in the late summer and fall.
Rings of trees growing in temperate climates can indeed tell their age through their annual rings and also help determine the age of wood used to construct buildings or wooden objects.

There were multiple theories of evolution prior to Charles Darwin's theory of evolution, some being from the antiquity, some just 300-200 years old.
One of the theories of evolution was the theory of hybrids. This theory was proposed by the great natural scientist Carl Linnaeus in 1744.
His theory was that initially God created small number of species, and placed those species on an isolated island. Over time, the created species started to breed between each other. That created numerous different hybrid offspring. These hybrids were actually new species, created by the breeding between the different species, and over time they developed into the numerous species we now of.
