Human Evolution: Neanderthal Relationship Explained
This question requires understanding the evolutionary link between modern humans (Homo sapiens) and Neanderthals (Homo neanderthalensis).
Analyzing the Statements
-
Option 1 Incorrect: Modern day humans evolved from Neanderthals.
This is incorrect. While there was interbreeding, modern humans did not descend directly from Neanderthals. They represent distinct lineages that diverged earlier.
-
Option 2 Correct: Modern day humans and Neanderthals share a recent common ancestor.
This statement aligns with current scientific consensus. Both Homo sapiens and Neanderthals evolved from a common hominin ancestor that lived in Africa approximately 500,000 to 800,000 years ago. They are evolutionary cousins, not ancestor and descendant.
-
Option 3 Incorrect: Modern day humans and Neanderthals both evolved from chimpanzees.
This is incorrect. Chimpanzees are our closest living primate relatives, but humans and Neanderthals evolved from much earlier hominin ancestors, long after the lineage leading to humans diverged from the lineage leading to chimpanzees.
-
Option 4 Incorrect: Modern day humans evolved from chimpanzees.
Similar to Option 3, this is incorrect. Humans and chimpanzees share a common ancestor, but humans did not evolve *from* chimpanzees.
Conclusion
The most accurate statement based on evolutionary biology is that modern humans and Neanderthals share a common ancestor.
Important Questions from Phylogenetic trees
- Newts produce tetrodotoxin (TTX), a poison that targets sodium ion channels, for defense against their predators, garter snakes. Several species of garter snakes are resistant to newt TTX due to specific known amino acid substitutions in garter snake sodium channels. Which one of the following is best-suited to identify whether this adaptation in garter snakes has a single origin or multiple independent origins?
A phylogenetic tree representing the evolutionary relationship between various vertebrates is shown below.
Given this tree topology, which one or more of the following statements is/are correct?A phylogenetic tree for the evolution of two pigmentation traits in species of fish is shown for clades X, Y and Z. Genes A and/or B, if mutated, can cause dark pigmentation in the body.
Which one or more of the following statements is/are correct?- Whales and dolphins are hypothesized to have evolved along the northern shore of the Tethys Sea, prior to the Indian plate's collision with the Eurasian plate. To which one of the following animals are these aquatic mammals most closely related?
In the phylogenetic trees shown, the tips represent different species of geckos(labeled A to E) and the areas to which they belong. Which one of these is most consistent with the hypothesis that the geckos colonized the Western Ghats from Northeast India through the Eastern Ghats?
