EVOLUTION FOR KIDS - Common Core History 1

Оценок: 168 | Просмотров: 35371
A Kid Explains History presents a new series based on the US Common Core State Standards Initiative. This World History curriculum is what kids like Mr Q will be taught at elementary and middle school, so he decided to take a look and share what he's learned. Whether you're a fellow student or an adult who wants a refresher, join the #historysquad and discover the wonders of our collective story.

One way to understand Evolution is to first understand “Artificial Selection”. Wolves and Dogs are descended from common ancestors (which looked more like modern wolfs than dogs). Over many generations, Humans selected the “favourable” traits (e.g., long shiny fur, or stocky legs etc) to produce the many different types / breeds of modern dogs that we have today. The keyword here is “over many generations”. There are modern dogs that, of course, are still very much wolve-like in appearance (e.g., Huskies, German Shepherd etc). Some dog breeds are much less wolf-like in appearance (Chihuahua, Shih Tzu etc) as they have been artificially selected for their small size and “cute” traits. So why is it known as artificial selection? This is because the Human (the dog breeders) are the ones determining which individual dogs they would prefer to produce offsprings, thereby continuing the genes they would like to retain. Prior to this, it is also important to understand the idea of Variation. This means that in a litter of puppies, not every puppy is physically identical (even though they may look identical to the untrained eyes). Some puppies have slightly longer legs, some shorter legs. Very small differences, but, yes, the differences are there. It is due to this physical variations that the breeders (humans) select which dogs possess the traits he wants, thus the term “Artificial Selection”. This Selection process is repeated over many generations and the result is the modern dog breeds we have today. Once we understood Artificial Selection, it will be easy to understand Natural Selection. In Natural Selection, the environment aka Mother Nature (instead of Human) is the factor deciding which traits survive through the generations. How? One example is Food Source. Many species of birds have developed the ability to swim to obtain their food (Adaptability). One pre-requisite of aquatic birds is having water-proof feathers. In this case, this is the “Favourable Trait”. One group of birds may live nearer to the seasides and Individual birds with better waterproof feathers is seen by Mother Nature as a “favourable trait”. And so individual birds with this trait has a much higher chance of survival and passing on this gene to the next generations. Birds with “less waterproof” feathers may probably not even live to adulthood as they had difficulties obtaining their food (in the sea), resulting in their genes being eliminated from this group of birds. Using an analogy, you may think of this process as a kind of filtration process, where only the finest particles is able to pass through the fine filter. This is Adaptation, and it has to be highlighted that Adaptation takes place over many, many, many generations. Physical Adaptations (e.g., change in body shapes) DO NOT take place in just one generation. In other words, an individual animal will not change its form physically to obtain that trait in its lifetime, unless it’s metamorphosis which is a totally different thing. We also observed this in rabbits living in deserts and rabbits living in cold countries. The long ears in rabbits act as effective heat radiators. This enables the rabbits to lose body heat efficiently, just as how humans lose heat efficiently by sweating. The rabbits living in deserts adapted (over many generations) to the environment by developing very long and erect ears for highly efficient lowering of their body temperature. But rabbits living in cold countries tends to have shorter ears (some even have lop ears). Shorter ears is the “favourable trait” here as it enables them to lose less body heat. All animals (and yes, that includes Humans) are still in the midst of Evolution. If Evolution is constantly ongoing, why can’t we see it happening? We need to understand that Evolution is a very, very slow on-going process. Evolution will never be “complete”, as change is the only constant. If Evolution is true, why are there no animals that are “neither here nor there” (i.e., in-between two species)? We need to remember humans are the ones who gave distinct names to different distinct species of animals in the first place. Let us look at the Seals / Walruses. Their ancestors are land animals, but their body shapes (flippers and hydrodynamic bodies) are hard evidence that they are in the midst of “transition” from land animals to aquatic animals, as their main source of food is in the sea. Of course, we cannot see an appreciable change in their appearances in our lifetime, as the change is happening far too slowly over many generations. So presently, we can only imagine the current physical appearances of Seals / Walruses as being “frozen-in-time”, as with the rest of the millions of species of animals currently living on this planet Earth. And do appreciate their beauty in their current physical form (and the diversity of the Tree of Life), as they will never be the same again one million years from now.

you are very smart.

Kid have looked into the absurd claims/theories of evolution? With all do respect you are doing your studies but question what you been taught. Everything.
Juno Donat (1 месяц назад)
Why are they absurd? They are not mere claims but what the evidence leads us to conclude. (Evidence = DNA, domestication, reverse engineering, comparative anatomy, fossils, etc.). The Bible is nothing but claims without evidence. Virgin births, talking snakes, etc.

Im watching human evolution YOUNG
Vimal Sehgal (4 месяца назад)
There is no evidence whatsoever that one species evolves to become another species. Humans always give birth to humans birds to birds monkeys to monkeys and donkeys to donkeys.
Juno Donat (1 месяц назад)
+Vimal Sehgal I didn't insult you.
Vimal Sehgal (3 месяца назад)
noahthelibertarianatheist The only proof evolutionists have to offer is insult creationists. Bunch of primitive retards. After all what else can one expect from descendents of apes ?
Darwinist Deist (3 месяца назад)
+Juno Donat yup but he's a creationist so don't expect him to understand too much
Juno Donat (3 месяца назад)
And please refrain from making assertions about there being no evidence just because YOU have not exposed yourself to the evidence. Or perhaps you deny the evidence due to your religious conviction.
Juno Donat (3 месяца назад)
One species "giving birth" to another species is NOT evolution. Evolution is genetic change over successive generations. These genetic changes correspond to changes in morphological features. Therefore, gradual changes that accumulate lead to the classification of a new subspecies, or species as apart from the ancestral or parent group. The term "species" is arbitrary (and without a fixed delineation) and is used only to classify an organism, or distinguish between them, at a particular point in time.

Great video, can't wait to show it to my daughter who is turning 6 this August.
A Kid Explains History (4 месяца назад)
Thank you! We hope she enjoys it.

Stop it! Your wrong! Evolution never happened God loves you more than you can think, this video shows no real evidence at all your just saying stuff and showing pictures. Jesus is coming Jesus is coming soon! So give your life to Jesus Christ now!
steven G (2 месяца назад)
lol there is plenty of evidence of evolution you ignorant moron. though none of god funnily enough you hypocritical brainwashed fool.
Juno Donat (2 месяца назад)
+debbie duran ...take your meds. There is evidence and people who understand it are what we call "smart people" - you have excluded yourself from that category.
debbie duran (2 месяца назад)
Perfect example how the education system is flawed. This is a belief without evidence. Doctrine of devils. GOD is real.
steven G (5 месяцев назад)
where's your real evidence of God then you brainwashed hypocrite. And please don't just say stuff and show pictures...
Juno Donat (5 месяцев назад)
Mr.FlamingoYT Human beings have been creating gods throughout history, yours is no different, and ancient people believed in their gods are strongly as you believe in yours. Evolution and common descent is solid science and is supported by volumes of evidence spanning multiple disciplinary fields. It underlies modern medicine and is the foundation of what we know about ourselves and the world we live in.
