Animals that possess homologous structures probably _____
Animals that possess homologous structures probably have a common ancestor. Homologous structures are physical characteristics that are similar in form or function, but may serve different purposes in different species. These structures are believed to have evolved from a common ancestor and are thought to be evidence of the evolutionary relationships between species.
For example, the wings of birds, the wings of bats, and the forelimbs of humans are all homologous structures. They all have the same basic structure, with bones arranged in a similar way and muscles that allow for movement. However, while the wings of birds and bats are used for flying, the forelimbs of humans are used for a variety of purposes, including walking, grasping objects, and communicating through gestures.
The existence of homologous structures is one of the key pieces of evidence for evolution, as it suggests that different species have shared a common ancestry and have evolved from a common ancestor. This is supported by the fossil record, which shows a clear progression of species over time, with new species emerging and old species becoming extinct.
In conclusion, animals that possess homologous structures probably have a common ancestor, as these structures are thought to be evidence of the evolutionary relationships between species. The existence of these structures helps to support the theory of evolution and provides insight into the history and development of life on Earth.

Homoplastic structures can be the result of parallelism, convergence, or mere chance. Birds and mammals, however, are alike in having four-chambered hearts two atria, two ventricles. Animals sharing a great many homologies that were recently derived, rather than only ancestral, are more likely to have a recent common ancestor. C Experiments in genetics show that traits acquired during an individual's lifetime are inherited in the way proposed by Lamarck. Tree 1 and Tree 2 Applying the principle of parsimony to the trait "ability to fly," which of the two phylogenetic trees is better? Since the trees show different evolutionary relationships, you cannot determine which ismore parsimonious. A have increased genetic diversity. The nuclear genome of eukaryotes contains genes from archaeans and from bacteria.
Animals that possess homologous structures probably _____. animals that possess homologous structures
E The species may go extinct. A Genes mutate faster in whales than in humans or bats. D The population may change so much in adapting to the new environment that it is considered a new species. Have increased genetic diversity c. D The unequal abilities of individuals to survive and reproduce will lead to the accumulation of favorable traits in the population over generations. Think about an elephant again but this time in terms of non-visual traits. What is the most likely reason she gave you the lily? Using this kind of reproductive data for defining species from the fossil record is impossible since we cannot go back in time to observe interspecies breeding patterns and results.

E Poorly adapted individuals never produce offspring. Homologous proteins have arisen separately in many different animal groupscorrect answer: A homologous structure is an example of an organ or bone that appears in different animals,. Thus, modern extremophiles survive only in places that their ancestors became adapted to long ago. On discovering an unknown organism, researchers begin their classification by looking for anatomical features that appear to have the same function as those found on other species. Both of these very distinct species lines solved the problem of getting off of the ground in essentially the same way. Are not related e.
