Adult female in natural habitat, Samaria Gorge National Park The kri-kri (Capra hircus cretica), sometimes called the Cretan goat, Agrimi, or Cretan Ibex, is a feral goat inhabiting the Eastern Mediterranean, previously considered a subspecies of wild goat. The kri-kri is now found only on the island of Crete, Greece and three small islands just offshore (Dia, Thodorou and Agii Pantes). The kri-kri has a light brownish coat with a darker band around its neck. It has two horns that sweep back from the head. In the wild they are shy and avoid humans, resting during the day. The animal can leap some distance or climb seemingly sheer cliffs. The kri-kri is not thought to be indigenous to Crete, most likely having been imported to the island during the time of the Minoan civilization. Nevertheless, it is found nowhere else and is therefore endemic to Crete. It was once common throughout the Aegean but the peaks of the 2,400 m (8,000 ft) White Mountains of Western Crete are their last strongholds—particularly a series of almost vertical 900 m (3,000 ft) cliffs called 'the Untrodden'—at the head of the Samaria Gorge. This mountain range, which hosts another 14 endemic animal species, is protected as a UNESCO Biosphere Reserve. In total, their range extends to the White Mountains, the Samaria National Forest and the islets of Dia, Thodorou, and Agii Pandes. Recently some were introduced onto two more islands. By 1960, the kri-kri was under threat, with a population below 200. It had been the only meat available to mountain guerillas during the German occupation in World War II. Its status was one reasons why the Samaria Gorge became a national park in 1962. There are still only about 2,000 animals on the island and they are considered vulnerable: hunters still seek them for their tender meat, grazing grounds have become scarcer and disease has affected them. Hybridization is also a threat, as the population has interbred with ordinary goats. Hunting them is strictly prohibited. Minoan rhyton from the Palace of Zakros, depicting a rocky landscape with Cretan goats. Archaeological excavations have unearthed several depictions of the kri-kri. Some academics believe that the animal was worshiped during antiquity. On the island, males are often called 'agrimi' (, i.e. 'the wild one'), while the name 'sanada' () is used for the female. The kri-kri is a symbol of the island, much used in tourism marketing and official literature. As molecular analyses demonstrate, the kri-kri is not, as previously thought, a distinct subspecies of wild goat. Rather, it is a feral domestic goat, derived from the first stocks of goats domesticated in the Levant and other parts of the Eastern Mediterranean around 8000-7500 BCE. Therefore, it represents a nearly ten-thousand-year-old "snapshot" of the first domestication of goats. In any case, the kri-kri is an emblem of Crete and has immense cultural significance there. Legally however, endangered species legislation would likely not apply (as this does not cover feral populations), but similar cases elsewhere have been covered under cultural heritage protection laws.

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Capra hircus has left across the world's sequence archives.
At a glance
★ the standard DNA barcode for this group — the short region actually read to tell this species apart. The rest are extra genes sequenced along the way.
Besides the big genome in the nucleus, cells carry a small, circular loop of DNA inside the cell's energy factories — the mitochondria. It is inherited almost only from the mother and is a leftover from ancient bacteria that moved into the cell. The mitochondrial markers above (ND*, COX, CYTB…) are read from exactly this loop. Outer ring = one strand, inner ring = the other.
The complete instruction manual Capra hircus carries — its genome. We read it from three angles — how big it is, how the DNA is packed into chromosomes, and how completely it has been sequenced — and explain how to read each value as you go.
Genome sizehow big the whole instruction manual is
Measured in base pairs (bp) — the individual letters of DNA (human ≈ 3.2 Gb, a bacterium a few million). The chart places this genome on a logarithmic scale — each step to the right is ten times bigger — among reference organisms. Across species a bigger genome loosely tracks with larger cells, slower growth and lower-energy lifestyles (powered flight favours small genomes) — yet it does not imply more genes or a more advanced organism (the long-standing C-value paradox).
Chromosomes & ploidyhow the DNA is packaged
2n is the full chromosome count in a normal body cell; n is a gamete (egg or sperm), which carries half. Ploidy is how many complete chromosome sets each cell holds — 2× (diploid) is typical for animals, while higher levels (polyploidy) are common in plants.

Sequencing statusassembly quality — how far to trust these numbers
Assembly level tells you how finished the sequence is — from fragmented contigs, through scaffolds, up to a full chromosome-level assembly. BUSCO % estimates completeness: the share of genes expected to be present that were actually found. These describe the data quality, not the organism.
How far back this lineage goes — and how we know. Everything here is measured in Ma, short for “mega-annum”: millions of years ago. The chart reads left to right like a calendar of the Earth, from the deep past on the left to today at the right edgetop to bottom like a core drilled through the Earth, from the deep past at the top down to today at the bottom.

When this lineage existed
How to read this: the coloured strip along the bottomdown the left is the geological calendar — the standard epochs (Pliocene, Pleistocene…) every museum uses, shown so you can see which chapter of Earth's history this lineage lived in. This lineage is a young one, so the strip is zoomed in to epochs — the finer subdivisions inside a period. The solid bar is the fossil range: the span between the oldest and the youngest fossil that palaeontologists have assigned to Capra hircus. Above itBeside it, the bars count how many dated finds fall in each slice of time; the tallest bar is labelled, and heights use a square-root scale so that thin slices stay visible next to rich ones. Read this as how well each stretch of time is preserved and studied — thick bars mean plenty of the right kind of rock and plenty of collectors, which is related to, but not the same as, how common it actually was. The orange marker is the DNA clock: DNA accumulates mutations at a roughly steady rate, so comparing this species' DNA with its relatives estimates when the lineage split off — independently of any fossil.
The two clocks disagree here. The fossil record reaches back to 7.25 Ma, but the molecular clock dates the lineage to only 0.93 Ma — about 6.32 Myr younger. A fossil cannot be older than the lineage it belongs to, so one of the two is off: either the fossil is assigned to the wrong species, or the clock is running fast.

Where the DNA of Capra hircus was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
