Provide evidence that living things involved from earlier species historical fictions religions fossils videos and dinosaurs
Fossils provide evidence that living things evolved from earlier species. Fossils are the remains or traces of organisms that lived in the past. They provide a record of the history of life on Earth, including the evolution of different species over time.
Additionally, evidence from genetic analysis, anatomical comparisons, and observations of natural selection in action also support the theory of evolution. For example, scientists have found that the DNA of different species contains similar sequences, indicating a common ancestor. Anatomical and physiological similarities between different species also suggest that they share a common ancestor.
Furthermore, the fossil record has provided evidence of the existence of dinosaurs, which roamed the Earth millions of years ago. These fossils have also provided important insights into the evolution of birds, which are believed to have evolved from small, feathered dinosaurs.
In contrast, historical fictions and religions are not scientific evidence for evolution, as they are not based on empirical data or observation. Similarly, videos may provide educational content about evolution, but they are not themselves evidence for it.
To determine the probability of a child having a widow's peak when both parents do not have a widow's peak, we need to consider the inheritance pattern of this trait.
According to the information provided, having a widow's peak (W) is dominant over not having a widow's peak (L). This means that if a person has even one copy of the widow's peak allele (W), they will express the trait.
Let's denote the parents' genetic makeup:
- Parent 1: LL (not having a widow's peak)
- Parent 2: LL (not having a widow's peak)
Since both parents have the same genotype (LL), they do not have the widow's peak allele (W) to pass on to their child. Therefore, there is no possibility for the child to inherit the widow's peak trait.
Therefore, the probability of their child having a widow's peak is 0%, as there is no genetic contribution of the widow's peak allele from either parent.
