What is the difference between radiocarbon dating and dendrochronology

All life on Earth uses a three-letter code to produce 20 standard amino acids.Researchers have artificially expanded the genetic code to produce additional amino acids as tools, but all natural life use the same 20 amino acids from our common descent.The continents drift at a rate of a few centimeters a year and the distance between the Americas and Africa is 455,000,00 centimeters.There are matching fossils on both sides of where the continents appear to have split apart.Mutations that give an organism a survival and reproductive advantage will be more likely to show up in offspring.Genes that code for proteins are composed of three-nucleotides (U/T, A, G, or C).By measuring the ratio of carbon-14 in a younger fossil, scientists can estimate its age.

You will never find a Neanderthal bone in the same stratum as a Tyrannosaurus rex bone.

Plants take in carbon from the atmosphere and ocean and fix it into themselves.

Animals eat plants and fix the carbon into themselves.

When a species gets split into two groups by a river, mountain range, island, lake, or ocean via earthquakes, floods, droughts, climate change, or continental drift, the two populations will begin to drift genetically.

Mutations that reduce an organism’s ability to survive and reproduce will be less likely to end up in offspring.

    Ben voor de rest vrij rustig van karakter, lichtjes introvert/verlegen, eerder meegaand, zeker geen moeilijke mens :-) Voorkeur voor hetzelfde type, rustig en liefst geen macho of modellentype (en als het effe kan ook nog eens uit de buurt van West en Oost-Vlaanderen MAAR dat hoeft niet perse).
