The process of permineralization, where mineral deposits form internal casts of organisms, provides us with a vast quantity of fossils that give us an idea of the different forms life has taken in the past.
Speciation is the process by which new species are formed.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.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.Tyronnosaurus rexes weren’t alive at the same time; therefore, their stratum didn’t get laid down at the same time.
Benjamin Franklin saw that there were fossilized sea shells on top of the mountains of Appalachia, some of them imprinted into solid rock, and concluded, “Tis certainly the Wreck of a World we live on!
Plants take in carbon from the atmosphere and ocean and fix it into themselves.
Animals eat plants and fix the carbon into themselves.
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).
