Concept explainers

Human Evolution

Human evolution is the process of evolution of humans from early man to anatomically modern humans. The process of evolution in humans leads to the gradual development of traits like bipedalism. Humans are the highly social animals that make them the most advanced animal on Earth. Human evolution is an outcome of interaction among the following processes:

Question

POSSIBLE POINTS 20

exoskeleton.

Insects have three thoracic (trunk) segments. While researchershave found insect fossils with pairs of wings on all threesegments, modern insects have wings or related structureson only the second and third segment. It turns out thatin modern insects, Hox gene products act to inhibit wingformation on the first segment. The treehopper insect (above)is somewhat of an exception. In addition to having wingson its second segment, the treehopper’s first segment has anornate helmet that resembles a set of thorns, which a recentstudy has found to be a modified, fused pair of “wings.” Thethorn-like structure helps to camouflage the treehopper intree branches, thus reducing its risk of predation. Explain howchanges in gene regulation could have led to the evolution ofsuch a structure.
Subject : General Biology 2 *Evolutionary Relationships of Humans to Other Vertebrates* Determine the Evolutionary Relationship of Human to Other Primates and Vertebrates using a Phylogenetic Tree **pls the handwriting, pls be readable i have terrible eye sight huhu thank you* *pls just don't copy the answers in the internet, i know how to used google so i used this app to have a unique and non plagiarized answer thank you* (experience this things in this app :< so i kinda traumatized)

The Evolution of the Stickleback Fish. Watch the ~15 minute video, Making of the Fittest: Evolution of the Stickleback Fish (https://youtu.be/Pv4Ca-f4W9Q) and the 1 minute video “Stickleback Fish Environment” (https://youtu.be/IRqLy3Oz-oM), both from the Howard Hughes Medical Institute. Answer the questions that follow: True or False? Having pelvic spines is always advantageous to a stickleback. In one sentence, explain your answer. True or False? Dramatic changes in traits, such as the loss of limbs, can occur through mutations affecting a single gene. Provide evidence for your answer. Below is a simplified schematic representation of some of the genetic elements involved in the regulation of Pitx1 gene expression (from HHMI BioInteractive). The large grey rectangle represents the protein-coding region of the Pitx1 The smaller rectangles to the left (b and c) are regulatory switches (networks of regulatory genes); each one allows a specific binding protein to interact with it and…
