Many animals, from the very large to the odd lived during the ice age. Harlan’s Ground Sloth seems to be one of the most bizarre animals from that era. A mix of large and odd, these large, furry animals are related to modern sloths, armadillos, and anteaters. Unlike its smaller modern cousin, Harlan’s ground sloths could be as tall as modern elephants and as heavy as a small car.
Sheer size was not the only odd part of a Harlan’s ground sloth. These giants were bulky, with short necks, powerful chests, and massive jaws. The sloth also had three claws per hand for digging, grabbing, or defending themselves. Just like armored armadillos today, the sloth had a protective coat of rough, brown fur, with nickel-sized bone plates underneath their skin. Scientists called this the “dermal ossicles” or bone skin
Ground sloths migrated to North America during the ice age. They spent their lives wondering open-grasslands with water sources, like rivers and lakes. Using its stubby snout and sense of smell, the sloth may have found and eat grasses, shrubs, and plants with flowers. The need for water sources may have brought Harlan’s Ground Sloths to New Mexico and southern US during the ice age. Before the sand dunes existed, a giant lake called Lake Otero filled the area. It provided a water source that attracted many ice age animals, including Harlan’s Ground Sloths.
Today on the old dried lakebed of Lake Otero or Alkali Flat, New Mexico, Harlan’s Ground Sloths left clues that they were here. Many fossilized footprints are visible. They had crescent shaped footprints. Their back feet twisted inward when they walked. This made them walk slowly, almost like waddling. These large strong slow moving animals became easy targets for daring predators such as Paleo-Human hunters.
The Giant ground sloth of course does not live today. Around 10,000 years ago, the large ice age animals died out. Scientists still debate why the larger animals disappeared. The Harlan ground sloth is reminder of a time long past however with modern technology maybe one day could be brought back.
In 1963, despite fact project would eventually flood dozens of modern villages and ancient sites. The government of Syrian Arab Republic, decided to create dams on upper Euphrates river. Culminating a series of excavation and archaeological rescue operations. Among them, an extraordinary neolithic site. Abu Hureyra. In a short span of less than 35 years. They gathered more information about the human being transition to agriculture, then anywhere previously; with more details. Using + setting the standard for new techniques, and with less time.

Popular and common amongst insect collectors, the peppered moths, are easy to preserve, and maintain after death. How easily though, there populations can adapt to new conditions in times of environmental stress. Before 1850, the moths were speckled light grey, after 1850, peppered moths, started turning darker, almost totally black. Was it evolution through natural selection, or Darwinism? It was no doubt, industrial pollution, in England, mid 19th century, turning lichen on tree trunks black. Many white, (or lighter coloured peppered moths), were easy to identify and thus vulnerable to predators. As more of the dark moths survived, the gene pool shifted toward darker colourations. Similar ‘industrial mechanisms’ were identified all over the world. For about 100 years, dark peppers moths continued to dominate the population. Then, in the 1950s, resulting from stronger anti-pollution legislation, air was cleaner, lichen went lighter, and so began the moths. The colour of the peppered moth definitely shifted in response to environmental factors however it was more multifaceted that thought (migration and birds). In short, story highlights environmental and neolithic complexities, and reminds us: be careful, simple evolutionary changes, aren’t that easy to trace.
Did your log cabin roof spring a leak? Is there now mould on the logs, mice and rodents are licking. Did the mould attract ants, termites and other pest? Are you trying to dry it out with the wood fireplace? Is the power out and do you need something sanitary to heat cloths, boil water, dry clothes and blankets??
Are there birds and bats in chimney? Did they attract larger critters? A bobcat, cougar, raccoon, cat, marten or bear? That is now trapped inside. Did it die? Causing smell, smoke, in house; as well, large, black, florescent blow flies??
In your home, do you have a waterfall feature, and your cats are scaring the goldfish inside it, causing them to splash a leak that attracts both mice, and ants. Were the cats taunted outside by raccoons?
