Villanovan Culture: Iron Age Italy and Its Unique Pottery
Villanovan Culture
The Villanovan culture was an Iron Age civilization in northern Italy, in the region that was once the seat of Etruscan culture. The name comes from the type locality, Villanova di Castenaso (near Bologna).
At the end of the second millennium BC (1200 BC), Indo-European peoples arrived on the Italian peninsula, connected to the Sea Peoples. This migration led to changes in the early Iron Age, resulting in the Villanovan culture. A pre-Indo-European fusion with Indo-Europeans occurred,

Plastids are a group of organelles unique to plant cells, varied in shape and size, delimited by a double membrane, and containing circular DNA. All plastids are derived from proplastids, undifferentiated structures present in dividing cells of plant roots and shoots. Depending on the needs of the differentiated cells, proplastids give rise to different types of mature plastids, which can transform from one type to another. All the plastids of a cell are called the plastidome. There are several types |
Tracing Human Evolution: From Early Primates to Homo Sapiens
II.2.2. Human Evolution
Geologists divide Earth’s history into eras, periods, and epochs. Life began about three or four billion years ago. Around 600 million years ago, the first animals large and hard enough to leave abundant fossils appeared. The phylum of chordates, the subphylum of vertebrates, and the superclass of tetrapods were present in the Devonian Period (300-400 million years ago). Mammals appeared during the Mesozoic Era (200-150 million years ago). Towards the late Mesozoic or early

Descartes’ Method: Rules, Doubt, and ‘I Think, Therefore I Am’
The Method
Rules guaranteeing the acquisition of clear knowledge.
The fundamental rules of the method are:
1. Rule of Evidence: Accept as true only what is presented with evidence (intuition). This leads to methodical doubt and establishes knowledge as a strict science. In “Principles of Philosophy,” Descartes states we never mislead if we only describe judgments based on clear and distinct knowledge. Error arises from judging before having accurate knowledge; the will can go beyond clarity and distinction,
