![]() ![]() ![]() Colour vision – allows primates to tell when fruit is ripe.Orbit (eye socket) is closed off by bone.Reduced olfactory centre of the brain (as vision became more important than smell).Usually only have single young – difficult to carry twins in the trees.Clavicle (collarbone)is large as it helps strengthen the shoulder joint for hanging from branches.Limbs are plantigrade (the entire foot is in contact with the ground).Prehensile (grasping) hands and often feet.5 digits (fingers and toes) per hand or foot.Larger brain, especially the fore-brain: cerebrum They have four different kinds of teeth – incisors, canines, premolars and molars.ħ. They have an external ear and 3 middle ear bones (this allowed for more efficient hearing – other vertebrates have only one)Ħ. They (generally)give birth to live youngĥ. They (generally) have hair and sweat glandsģ. It is your job to now find out and think about how this change has happened, what is the change and what world changes, both abiotic and biotic may have been driving it! Easy!Īn introduction to mammals and the primatesĢ. That means our species has been developing or changing over time. What is a trend? Well its a A general direction in which something is developing or changing. If you want a basic introduction before learning the concepts of the standard read the following link Here Click on the begin the program link at the bottom of the page and it will start into the audio book. The ultimate guide to this topic that beats any text book is the Waikato University website. Human evolution Prezi from Nayland College. doi: 10.1089/ast.2010.0524įull notes from nobraintoosmall - this really is a great set of simple notes to use to start a mindmap or study notes. Revision poster to fill in from Mrs Horrell-Morrisonĭefining Life. One of the major pitfalls people have when considering evolution is that they don't recognize one of they key components to understanding this concept: evolution is gradual and is looked at through generations, not individuals, and within populations of the same species. NASA's working definition of life is a "self-sustaining chemical system capable of undergoing Darwinian evolution."Įvolution is any change in the allele frequencies of inherited traits in a population that occurs from one generation to the next. The variance in the forms of life and the myriad of diversity has led many men to ask how this has come to be. Life exists throughout the world in the smallest bacteria, in the largest whale, and anything in between. Biological evolution can happen only once from generation to generation / occurs over many generations.Įvolution is an explanation for a seemingly inexplicable topic: life. cultural evolution can happen within a lifetime / generation. Cultural evolution is the transmission / passing on / evolution of learned behaviour / ideas / knowledge / non genetic information.īiological evolution is fast while cultural evolution is slow.Biological evolution is the transmission / passing on / evolution of genetic information (from parent to offspring).Here are a couple of definitions to learn. It answers those important questions of why our fingers go wrinkly when they get wet and why we no longer swing between trees and like to sit in front of computers and learn stuff.This topic is all about patterns and trends, what were the patterns leading toward bipedalism, tool uses, culture and looking at the bigger ideas of our biological and cultural evolution as a species. sapiens) as well as looking at our divergence from the ape lineage around 7 million years ago. This topic covers how we have come to be over the last 170,000 years (modern H. However, I do want to know about where the human species came from. Where did I come from? Well I don't want to think about that.
