Setting the Pleistocene Stage 2.5 million to 11,400 years ago Glaciers advanced and retreated eleven times Ocean levels dropped and rose in response Glacial Maximum 20,000 years ago Interglacial Ocean rises restricted intercontinental movement, while enabling intracontinental movement Neanderthals, large mammals and their predators spread across the north Glacial Ocean drop enabled intercontinental movement, while restricting intracontinental movement Neanderthals and wildlife were driven out of the north, placing them in the path of expanding homo sapiens. www.AdirondackWildlife.org

Genus Homo - Humans Out of Africa Homo Habilis in Africa 2.3 to 1.4 million years ago Homo Erectus: Africa, Asia & Europe 2.2 million to 140,000 years ago Common ancestor with Habilis? Homo Neanderthalensis 150,000 to 30,00 years ago in Europe & Mid East Homo Sapiens African genesis 200,000 years ago Small group of Wanderers became Humanity’s Adams & Eves, leaving Africa 60-100,000 y.a. www.AdirondackWildlife.org 1. Homo Sapiens, 2. Neanderthal, 3. Early Hominids, Wiki
6
How Genus Homo Changed History Mastered Fire Warmth Cooking, about 250,000 yrs ago Security from dangerous Predators Short-faced Bear Saber Toothed Cat Dire Wolf Larger social groups made pre-Homo frugivore diet unsustainable Learned to scavenge Meat Hunting game Incredibly Dangerous Made Crude Tools and Weapons Erectus shows evidence of the “Throwing” Shoulder Neanderthals Converse & create totems? Homo Sapiens Developed Language & Animistic Religion – Oral Tradition? Pre Historic Cultures are extremely war-like www.AdirondackWildlife.org

Dire Wolf www.AdirondackWildlife.org Mark Hallett, Paleoart Pleistocene wolf Most common mammalian find in LaBrea Tar Pits Larger than Grey Wolf Driven to extinction about 10,000 years ago

Competing & Living with Wolves Competed for meat with Wolves & other predators Learned to steal Meat from Wolves Inadvertently Provided Meat for Wolves and other Scavengers at the Bone Pile Took in occasional orphaned wolf pup Wolves became early warning system for dangerous predators or intruders Provided Meat for Wolves at the Campfire Accidental tactical cooperation during hunting, with each exploiting the other species strengths & tactics Unnatural, forced selection led to dogs Geographical, Topographical & Glacial Isolation drove diversity in humans & their “dogs” www.AdirondackWildlife.org

Wolves and Dogs Wolf Packs are Families Wolves are territorial Wolf packs are hierarchical Dogs are like Wolves. Emotionally Transparent Living in the Moment Dreams & Actions Cats and Dogs Wolves are like People. Mom & Dad are the “Breeding Pair” Dogs are like Us. www.AdirondackWildlife.org

Dogs & People www.AdirondackWildlife.org Dmitri Belyaev 1959 experiment with selecting & breeding tame silver foxes Less adrenaline in Tamer foxes Shorter limbs & tails Floppy ears & curly tails Left gaze bias in both Humans & Dogs Sympathetic bias towards infant faces Neotonous selection for breeding Oxytocin release in dogs & owners Heart attack survival & occurrence Wolfs bark or “woof” as a warning Dogs developed barking to communicate with us 500 million dogs in the world, about 500k wolves Silver Fox, Wiki
18
Dogs & People www.AdirondackWildlife.org Natural Selection: Survivors Breed Unnatural selection, or “Eugenics”: Selected Traits Predominate & Become Exaggerated Decline of nature’s fitness restrictions allows alternate phenotypes, or “funny” looking dogs, to survive and breed Dogs were selected for cooperation, for responding to our social queues Dog’s olfactory orientation married to our visual orientation Tandem Repeaters more prevalent in Canids Physical Traits may be controlled by fewer genes, making selective breed alteration easier to achieve… …..While messing up pure breeds: 1 in 4 have genetic issues with recessive genes expressed. Independence from seasonal weather affects estrus frequency 80% of 300-400 breeds developed in last 130 years
19
DNA (Template) → RNA (Codon; sequence of 3 nucleotides) → Amino acid(s) → Polypeptide (Protein) www.AdirondackWildlife.org Genetics
20
The Speed of Evolution via Natural or Unnatural Selection Increases as the Rate of Mutations Increase Between Each Breeding With Regards to Canines, a high rate of mutations occurs due to: Tandem Repeaters Repeatable DNA sequences with a relatively high rate of mutations Canids have a much higher rate of tandem repeaters than other carnivores, and most other mammals SINE Elements Elements that leave one chromosomal location and insert themselves into another Canids have at least 11,000 SINE elements, humans have less than 1,000 www.AdirondackWildlife.org
21
How to cause a mutation 101: 1. Change in DNA Sequence 2. Change in mRNA Codon 3. Change in Amino Acid Produced 4. Change in Protein Structure (Mutant Protein) *The mutant protein may cause: 1.No change 2.Different physical trait 3.Improved function - Evolutionary advantage 4.Reduced function - Evolutionary disadvantage 5.Uncontrolled cellular division - Cancer www.AdirondackWildlife.org
