Please answer both the questions.I'll definitely give a like Transitional Fossils: Which of the following statementsis/are false regarding the limbs of tetrapods.O The pectoral fins of fish are related to the forelimbs oftetrapods.O The pelvic fins of fish are related to the hindlimbs oftetrapods.Fins are homologous to limbs.O The front limbs of tetrapods have a single bone at their base,the humerus.The wrist bones of the front limbs of tetrapods aresupported by a pair of bones, the radius and the ulna.O Ray-finned fishes have single bones in their fins homologousto the humerus and femur. Transitional Fossils: Which of the following is the correctsequence in the evolution of structures that facilitatedthe transition to terrestrial environments?Lungs > humerus > wrist > pelvis > neck > digitsLungs > humerus > digits >wrist > pelvis > neckO Lungs > pelvis > wrist > humerus > neck > digitsLungs > pelvis > neck > humerus > digits > wrist

As per our policy, we are answering the first question only. Kindly repost for other questions.…

Neanderthals are recognizably human but have distinctive facial features and a stocky build that were evolutionary adaptations to cold, dry environments. They shared Europe for 10,000 years with Homo sapiens. Today they no longer exist. Beyond these facts the fate of Neanderthals has generated much debate. Why did Neanderthalsbecome extinct? State at least two major factors toexplain their fate.
n. Scientists have found one new fossil that is similar to Archaeopteryx. It is only the second fossil of its kind. It shows an animal that had a long-feathered tail and small teeth, like non-avian dinosaurs. But the animal also had flight feathers and wings, like modern birds. The fossil also shows a fused clavicle bone, which confirms the relationship between birds and dinosaurs because they are the only two groups with this characteristic. What is true about this scenario? It shows evidence of evolution. It shows evidence of widespread expression. It shows evidence of climate change. It shows evidence of causation.

The diversity of modern vertebrates was shaped in partby mass extinctions. The most severe extinction eventwe know of occured at the border between the Permianand Triassic periods about 250 million years ago. Anestimated 96 percent of the marine species and 70 percentof land species disappeared in what is sometimes called“The Great Dying.” The cause of this mass extinctionremains under investigation. Suggested causes includean asteroid impact, extreme volcanic activity, or a sudden release of carbon dioxide from deposits on the sea floor. Which groups of vertebrates were present when this mass extinction event occurred? Which evolvedafterward?

How did all the different body types in the Cambrian arise so quickly? O Hox genes had evolved that determine and allow for the diversification of body plans. Because Hox genes hadn't evolved yet, there was a lot of flexibility in how body plans could develop. O There was a genome duplication event that led to the diversification of body plans. Enhancer driven gene expression had just evolved, which made it easier to vary body plans. Toing wheroptiones 29
