Also, some scientists think it’s impossible for certain animals and not for others. For example, science says that they can’t get enough DNA from dinosaurs to be able to bring them back because they only have fossils. Wooly mammoths may be easier because their bodies have been frozen in ice making it easier to take the DNA and put it in elephants. This process can bring animals back that can affect our ecosystems in a very big way. They can also alter the ways of life in those ecosystems.
Besides, with the decision to bring back mammoth to life, scientists should be prepared with what will the mammoths eat? Scientists assumed that the diet would be same with the current living elephants including grasses, shrubs and all. With the expectation, people now are looking at the risks that might come with their croplands. What would stop mammoths from raiding these fields? How would human treat the beasts if they are misbehave?
Clones require a somatic cell nucleus and a fertilized egg cell sans nucleus. The genetic scientists in Jurassic Park obtained dinosaur DNA from blood in fossilized mosquitoes. Presumably, the genetic material came from white blood cells, considering that red blood cells have neither a nucleus nor DNA. To clone the
Their first discovery consisted of a few pieces of a knee bone. At first, Johanson thought the knee to belong to a baoon or monkey, but it didn’t seem like it belonged to such an animal (“In search of Human Origigins.” Nova, PBS, 3 June 1997. .pbs.org/wgbh/nova/transcripts/2106hum1.html) He sent the bones to an anatomist and part-time forensic expert, Owen Lovejoy. After examining the bone fragments, Lovejoy concluded that they appeared human; the joint could “lock”, suggesting the animal could walk upright. This was an important discovery showing an ancient bipedal creature.
The bold idea to establish grizzly surrogate mothers is one of the strategies proposed to counteract this problem and ensure a long lasting population. Grizzly bears are genetically similar to polar bears but are different because they have adapted to survive in warmer conditions. This is one of the main reasons they are still seen more often today. If the population of polar bears were to drop drastically, then we would be forced to look at the grizzly mothers as one of our only options. The transplant of polar bear embryos into grizzlies is all it would take to keep the declining population at a steady and safe
This is why I am interested in this topic because it seems to make a lot of sense because species evolve through natural selection, changing and adapting and then becoming extinct. If that were true, then where does Bigfoot fall in this category especially a creature that we know little about? So The Bigfoot-Giganto Theory actually comes to play and explains the evolution process of Bigfoot. I am also interested in this topic because as long as I can remember hearing about Bigfoot and its existence has me wondering where did Bigfoot come from? Where did this creature evolve from?
141). Fossils help provide evidence of the earth’s past and its developments (article 5 paragraph 4). Plus, fossils help gain interest in paleontology and earth’s natural history (article 1 paragraph 1). Dinosaur bones can help researchers have a more specific idea of how dinosaurs developed over time (article 7 paragraph 15). Fossil trading should not be allowed by governments all over the world because illegal dealers are not careful when digging out bones and fossils, fossil trading will lose years of scientific studies and people will not get to enjoy them as much, and it can result in a lot of trouble and/or embarrassment for private collectors or businesses.
Some of the animals will have traits that the breeder wants to preserve. In artificial selection, humans select animals over centuries, but nature takes hundreds of millions of years. So, the different breeds of dogs are considered to be different species because they cannot interbreed for mechanical reasons. David Attenborough, who presented in the movie, “Charles Darwin and The Tree of Life”, saw the biggest flower and the biggest creature in the world which is the blue whale. He discovered a thousand of bats, 200 different kinds of monkeys, 315 humming birds, 350,000 species of beetles and a quarter million of flowers in which a variety is astounding.
Putting grizzly bears in the park “brings economic benefits worth tens of millions of dollars to the region”(NationalParkService). Although putting grizzly bear in the park can promote tourism development, it is true that many living beings was hurt by grizzly bears, especially human
So they will be there as a vestigial structure because the fur on the bottom of the feet is not hurting them. For the snow fox they needed it to travel on snow more efficiently Structure: Liver Function: To turn toxins unharmful Evolutionary Change: Analogous Structure and Human Involvement Explanation: The liver in the forest fox will grow to filter out the toxins of the water because of the human involvement. Humans are putting trash and oils into the water, so having a larger liver will help filter out the water when they have to drink it. This can also be a analogous structure because it is different sizes for every animal but it serves the same purpose. Structure: Fright and flight effect Evolutionary Change: Behavior Function: To run when it sees or hears something Explanation: This trait will be beneficial to the forest fox because if it hears a predator it will run due to the fright and flight effect.
After some of the bone were sent to the laboratory, Archaeologists soon realized that this wasn’t any ordinary skeleton; it was one over 9,000 years old. This skeleton, named the “Kennewick Man” due to its location in Kennewick, Washington, was the oldest, most well-reserved skeleton found in North America. Shortly after the remains were unearthed, controversy and debate surrounded the home and origin of the skeleton. “Archaeologist Dr. James Chatters, working on contract with the Benton County coroner, thought that the bones might not be Native American.” If this were proven to be true, it would cause massive waves in what we thought we knew about our science and history. Initially classified as “Caucasoid”, Chatters modified his
