the males compete to fertilize
Scientist usually test and conclude about new discoveries or finds, such as new species, genetic engineering, etc.
A scientist would conclude that the ancestors of the given animal DID have legs, but, that over time, they evolved to become legless. Some examples of this kind of evolution include snakes, whales, dolphins, and the extinct, superficially fish-like icthyosaurs.
Females of which species?
No, not all species have males and females. For an example, whip tail lizards are an all-female species.
yes because a single fossil is representative of a similar enough time period in history to conclude that they lived together as a group and had similar habits
Finding the same species of fossil in two different places would lead to the conclusion that conditions were similar at both places when the fossils were alive.
In monomorphic species, male and female appear quite similar. In dimorphic species, the males appear quite different from the females. (Life, the science of biology, 7th edition, chapter 23)
