The frog's vestigial thumb may provide some vestigial functions like clinging or handling prey. Like opposable thumbs in primates, it's a remnant from evolution, and may aid in survival-oriented activities or serve no current significant purpose.
The frog's vestigial thumb, much like opposable thumbs in primates, is believed to be a trait left over from previous evolutionary stages. While its function in frogs is not fully understood, it is suggested that vestigial structures like the thematic thumb could still retain some functional or minimal purpose, potentially related to clinging or handling prey. For example, in primates, the opposable thumbs and toes are an adaptive trait providing the ability to effectively grasp branches, cling onto surfaces, and hold objects which contributes vastly to their survival in arboreal environments.
Although in frogs the thumb likely doesn't grant the same mobility or dexterity as in primates, its presence may still aid in activities like feeding, movement, or escaping from predators. Also, it's important to note that not all traits are formed for survival or adaptive purposes and could be neutral or nonadaptive, serving no current significant function or benefit.

Well allliving organisms contain genetic information, stored in DNA and RNA molecules,which directs the functions of cells.
The general coding and structureof these molecules is universally shared by all organisms. Questions about theorigin of these molecules are fundamental to our understanding of the origin oflife on Earth.
Experimentslike the one conducted by Miller and Urey demonstrated that organic moleculescould have formed spontaneously in Earth's early atmosphere, and smallermolecules could bond together to build large organic molecules. Somescientists hypothesize that some of the first large organic molecules to formand self-replicate were RNA molecules, with DNA molecules forming much later. This is called the RNA worldhypothesis.
These early RNA molecules were probably smaller than the RNAmolecules in our cells today. They would have contained the codes for buildingspecific protein molecules from the amino acids present on Earth at that time.Proteins are necessary components of all living cells.
It means that all of us- every living creature- was built off the same genetic code.
