Question

If the species Homo logicus was determined to be viviparous and to have extremely low fecundity rates on land, we might expect that (A) Homo logicus could overpopulate its niche and should be controlled. (B) Homo logicus might be declared an endangered species. (C) Homo logicus would pose no danger to other species and would itself be in no danger. (D) Homo logicus would soon become extinct. (E) None of these events would be expected with certainty.

Short answer

Homo logicus might be declared an endangered species (Option B).

Step-by-step solution

Understand Key Terms

We need to understand the specific terms used in the question. 'Viviparous' means the species gives birth to live young rather than laying eggs. 'Low fecundity rates' imply that the species produces a small number of offspring.

Analyze the Implications

A species that is viviparous and has low fecundity typically has fewer offspring at a time. They may face challenges in maintaining population size if mortality rates are high or if the environment changes rapidly.

Consider Each Option

- Option A suggests overpopulation, which is unlikely with low fecundity. - Option B suggests endangerment, which is plausible due to low reproduction rates. - Option C assumes stability, which is questionable with low fecundity. - Option D suggests extinction, which is a risk with continued low reproduction. - Option E suggests uncertainty, which is reasonable given the lack of specific environmental context.

Evaluate the Most Likely Outcome

Low fecundity increases the risk of population decline, making Option B (that they might be declared endangered) the most plausible scenario under typical ecological conditions.

Conclusion

Given the species characteristics and the available options, Homo logicus might be declared an endangered species. Low reproduction rates often lead to such classifications.

Key concepts

viviparous species

Viviparous species are creatures that give birth to live young, rather than laying eggs. This method of reproduction is common in mammals, including humans. It is different from oviparous species, which incubate their offspring in eggs outside the mother's body. This live birth method offers several advantages.

• The young are typically more developed at birth and can better survive in harsh environments.
• Viviparous species often have more complex parental care behavior.

However, viviparity can limit the number of offspring a mother can have at one time. This strategy, while beneficial in stable environments, poses challenges when environmental conditions are adverse.

low fecundity rates

Low fecundity rates refer to the production of a small number of offspring over a given time. In ecological terms, fecundity can greatly influence a species' ability to maintain its population. Species with low fecundity often have higher investment in each offspring.

• These species tend to have fewer births, but each offspring has a better chance of surviving to adulthood.
• This approach contrasts with species that have high fecundity rates, which often produce many offspring with lower individual survival rates.

Low fecundity can be disadvantageous if the environment changes rapidly or if there is high predation. In such cases, the species might struggle to sustain its population.

population decline

Population decline occurs when a species fails to reproduce at a rate sufficient to sustain its numbers over time. This can happen due to various reasons, such as:

• Habitat loss, which reduces living space and resources available for the species.
• Environmental changes, which can make it harder for the species to survive or reproduce.
• Increased predation or competition for resources.

For species with low fecundity rates, even minor adverse conditions can result in a significant decline in population. Over time, a continued decline could lead to the species becoming scarce or even extinct.

endangered species classification

An endangered species classification is a label given to species that face a high risk of extinction. This designation serves to highlight the need for conservation efforts.

• It often leads to protective measures and conservation programs aimed at preserving both the species and its habitat.
• Being classified as endangered can attract funding for scientific research and conservation activities.

For species with low fecundity rates, such as Homo logicus might hypothetically be, the risk of becoming endangered increases. Their limited reproductive capacity makes it harder to recover from population declines, emphasizing the importance of conservation.
