Today's farm animals, such as cattle, pigs, and chickens, have been selectively bred for specific traits, resulting in faster growth rates, increased size, and enhanced production capabilities (like milk or egg yield) compared to their earlier counterparts. These changes are largely driven by advancements in agriculture, including selective breeding techniques and a focus on efficiency and profitability. Additionally, modern animal husbandry practices prioritize disease resistance and feed conversion efficiency, contributing to the significant differences observed today. The shift towards more intensive farming practices has also led to changes in animal welfare standards and living conditions.
The three-domain system recognizes fundamental differences between the Archaea, Bacteria, and Eukarya domains. These differences are based on genetic, biochemical, and structural characteristics that distinguish each domain from one another. This system has replaced earlier classification systems that grouped all organisms into either plants or animals.

It is possible that multicellular animals existed before the Vendian Period. Like the Vendian animals, earlier animals may have been soft-bodied, so they did not leave fossils. Or, paleontologists simply may not yet have found any earlier fossils.

Neanderthals and Cro-Magnons were Homo sapiens species, but differed from earlier human ancestors in terms of their physical characteristics, such as larger brain size and robust build. They also had more complex tools, used symbolism, and engaged in more sophisticated social behaviors like burying their dead. These differences likely contributed to their survival and success compared to earlier hominins.
