- In Oct 2022, a chilling discovery was made in Vuvatu, a country known for its extensive volcanic landscapes. Scientists found the remains of a large organism that had no resemblance to any current form of life on Earth. The organism also had no resemblance to any fossils ever found, including the very few fossils ever recovered from Vuvatu (fossils are rarely ever found in Vuvatu since volcanic landscapes are generally not conducive of fossilization). The world buzzed with the possibility that this was a crash site for an extraterrestrial body. An extensive study of the uncovered remains was conducted by many research facilities. Their conclusions regarding the organism’s features are listed below: Physical features: The organism has a surprisingly soft and malleable exoskeleton that reflects ambient light, creating mesmerizing patterns. In fact, the remains highly suggest that most of its body parts are soft and blubbery rather than rigid. Habitat: Given its relationship with…In Oct 2022, a chilling discovery was made in Vuvatu, a country known for its extensive volcanic landscapes.

Explain why so few remaining samples of these early rocks remain.
- Imagine that you have the DNA sequences fromthe intron of a gene in three species called A, B,and C. Species A and B are most closely related,while C is more distantly related. The sequencesof A and B differ by 18 base pairs, A and C differby 26 base pairs, and B and C differ by 28 basepairs. Fossils show that species A and B divergedabout 1.2 Mya, but there is no fossil evidence asto when the most recent common ancestor ofall three species lived. Use the genetic data toestimate that date. What assumptions are youmaking to get this estimate?A construction project required digging hundreds of feet into the ground, which exposed many discrete strata. After a thorough investigation, paleontologists do not find fossils of Tiktaalik or any similar species. Explain why this finding could not be used to refute the theory of evolution.aterials Spirochaetes are free-living, anaerobic bacteria that contain spiral-shaped cells. Nematodes are roundworms that are incredibly diverse and, as a group, have adapted to survive in all environments. Which of the following statements accurately describes the DNA of both groups? * pdates ades embers nferences The spirochaete genome is smaller than the nematode genome. Q Online Nematode DNA is circular. sela Spirochaete chromosomes are composed of just DNA while nematode chromosomes also include specialized proteins. on Periods 1 and 2 eriods MP1, Highschool chool MP3, Spirochaete DNA is linear. MP4 Operons are clusters of genes that are regulated as a group. They can be characterized as either repressible or inducible. What is the main difference between the two? * d Thu Fri INTL 1
- A skull of Homo Neanderthalensisis tested using carbon14. Palaeontologists are wondering about whether the Neanderthal was living at the same time as Homo sapiens, known to be living in the same area 45 000 years ago. Measurements shown the original amount of carbon-14 isotope present in the skull when Neanderthal died is only 1.56%. A) How old is the Neanderthal fossil? B) Could this Neanderthal have been living with Homo sapiens in this area at the same time?If it is possible asnwer all the following questions, if not, i would like to know about question 2 and question 3. thank you. 1. Why is the statement, humans evolved from monkeys, incorrect? 2. In recent years, strains of bacteria resistant to antibiotics have created serious health care challenges for our society. Based on what you've learned about natural selection, explain how the overuse of antibiotics could influence the evolution of bacterial diseases. 3. How does the peppered moth example demonstrate that evolution is directional? 4. Is is viable to believe both in creation and evolutionMicrotaxonomy ( Species and Speciation ) People who do not believe in evolution often cite the classic example of man presumably evolving from the apes. They oftern ask: if humans evolved from apes, why are there apes until today? How will you provide a convincing answer that there is no contradiction in the existence of apes and humans at the same time?
- 15) This is an artist's rendition of Tiktaalik. What features does the organism possess and what does that provide evidence for with respect to evolution?Researchers looking for fossils of the earliest life-forms face many hurdles. Explain why sofew remaining samples of these rocks remain.2)Life on eath started 4.6 billion years ago 4-5 thousand years old the same age as the first prokaryotes 65 million years old 3) which of the following stement decribes what all menbers of population share? They are geographically isolated from one another They are members of the same species They have identical genes They are temporally isolated from one another 4)During their early stages of development the embryos of reptiles birds and mammals look very similar.this suggest that bird and mamals are no longer undergoing evolution have undergone parallel evolution live in the same types of environments have a common ancestor
