Creating the best cladograms is not easy. Here are some of the challenges we face:

1. Data Limitations:

   • Fossil records are often incomplete, making it hard to see how species have evolved over time.
   • Sometimes, genetic information is either very limited or unclear.

2. Methodological Issues:

   • Different methods can give different results, making it tough to agree on conclusions.

3. Interpretational Biases:

   • Scientists can unintentionally bring their personal opinions into their studies, which can affect how they see relationships between species.

Solutions:

• We can use better computer methods to improve our analyses.
• Teaming up with experts from different fields can help us gather more complete and accurate information.
